You may find yourself wanting to set a default value in your select options in your\u2002Angular app on different occasions. From building a form to displaying a set of options, defining a default value for an option when the page first loads can make it easier for\u2002people to use.&nbsp;<\/p>\n\n\n\n<p>This can be particularly helpful\u2002when certain fields have a common or recommended default. With the two-way data binding and the form controls in Angular, you can handle such a scenario quite\u2002comfortably.<\/p>\n\n\n\n<p>In this blog post, let\u2019s discuss the various ways through which we can apply the default select value. You will also learn some best practices as well as\u2002some real-world examples in order to implement this in an efficient way.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-set-a-default-value\"><span class=\"ez-toc-section\" id=\"Why_Set_a_Default_Value\"><\/span><strong><strong>Why Set a Default Value?<\/strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Having a default value for a select option is more than a decorative feature; it is\u2002good for all of the following reasons :<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>User assistance: <\/strong>If there\u2002is a commonly selected value or recommended value, it can make form filling easier if it is preselected.<\/li>\n\n\n\n<li><strong>Form validation:\u2002<\/strong>The default value will ensure your form looks good when it loads by providing a text box that is already filled out and that aligns properly with other fields.<\/li>\n\n\n\n<li><strong>Better User Experience: <\/strong>A well-thought-out form with reasonable default\u2002values decreases user input, increasing user satisfaction.<br><\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-set-a-default-value-in-a-select-option-using-angular\"><span class=\"ez-toc-section\" id=\"How_to_Set_a_Default_Value_in_a_Select_Option_Using_Angular\"><\/span><strong><strong>How to Set a Default Value in a Select Option Using Angular<\/strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There are numerous techniques for setting a default value in a select option in Angular language. In this section, we\u2019ll cover methods using <strong>ngModel<\/strong>, the <strong>selected<\/strong> property, and <strong>Reactive Forms<\/strong>.<\/p>\n\n\n\n<p><strong>Basic Example of List:<\/strong><\/p>\n\n\n\n<p>HTML<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;select&gt;\n  &lt;option *ngFor=\"let item of options\" &#91;value]=\"item.value\"&gt;\n    {{ item.label }}\n  &lt;\/option&gt;\n&lt;\/select&gt;<\/code><\/pre>\n\n\n\n<p>TypeScript<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>options = &#91;  \n  { value: '1',  label: 'Option 1' },\n  { value: '2',  label: 'Option 2' }\n];<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-1-using-model-to-set-default-values\"><span class=\"ez-toc-section\" id=\"1_Using_Model_to_Set_Default_Values\"><\/span><strong><strong>1. Using Model to Set Default Values<\/strong><\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>If you&#8217;re using template-based forms, ngModel is your friend. One of the simplest ways to set a default value in a select option is by using the ngModel command. This directive allows for two-way data binding between the select element and a variable in your component.<\/p>\n\n\n\n<p><strong>Example:<\/strong><\/p>\n\n\n\n<p>\/\/Component.ts<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>export class AppComponent {\n  selectedCountry = 'US'; \/\/ Default selected value\n  countries = &#91;\n    { code: 'US', name: 'United States' },\n    { code: 'CA', name: 'Canada' },\n    { code: 'UK', name: 'United Kingdom' }\n  ];\n}<\/code><\/pre>\n\n\n\n<p>\/\/Component.html<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;select &#91;(ngModel)]=\"selectedCountry\" name=\"country\"&gt;\n  &lt;option *ngFor=\"let country of countries\" &#91;value]=\"country.code\"&gt;\n    {{ country.name }}\n  &lt;\/option&gt;\n&lt;\/select&gt;<\/code><\/pre>\n\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The [(ngModel)]=&#8221;selectedCountry&#8221; binds the selected value.<br><\/li>\n\n\n\n<li>The default selection will be &#8220;United States&#8221; when the component loads.<\/li>\n<\/ul>\n\n\n\n<p><strong>Best Practice:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Always ensure that your model value \u201cselectedCountry\u201d is initialized in the component class (component.ts).<\/li>\n\n\n\n<li>Just make sure that the default value is part of the option list of the select element so that it won&#8217;t trigger\u2002validation errors.<\/li>\n\n\n\n<li>ngModel is great for\u2002basic forms, but it&#8217;s usually not a good idea to use it for those long, complicated forms that have dozens of fields. In that case, you might want to use reactive\u2002forms.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-2-using-the-selected-property\"><span class=\"ez-toc-section\" id=\"2_Using_the_Selected_Property\"><\/span><strong>2. Using the Selected Property<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The next technique to set a default value is by utilizing the selected property directly on the option elements. In this approach, the selected property is bound to a condition that verifies if the option value and the required default value match. While possible, this is not recommended in Angular due to better alternatives like ngModel.<\/p>\n\n\n\n<p>Component.html<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>&lt;select&gt;\n    &lt;option &#91;selected]=\"color === 'red'\" value=\"red\"&gt;Red&lt;\/option&gt;\n    &lt;option &#91;selected]=\"color === 'green'\" value=\"green\"&gt;Green&lt;\/option&gt;\n    &lt;option &#91;selected]=\"color === 'black'\" value=\"black\"&gt;Black&lt;\/option&gt;\n    &lt;option &#91;selected]=\"color === 'white'\" value=\"white\"&gt;White&lt;\/option&gt;\n&lt;\/select&gt;\n&lt;p&gt;Selected Color: {{ color }}&lt;\/p&gt;\n<\/code><\/pre>\n\n\n\n<p>Component.ts<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>import { Component } from '@angular\/core';\n\n@Component({\n    selector: 'app-root',\n    templateUrl: '.\/app.component.html',\n    styleUrls: &#91;'.\/app.component.scss'],\n})\nexport class AppComponent {\n    color: string = 'green'; \/\/ Default value\n}<\/code><\/pre>\n\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The selected property is bound to a condition that checks if the `color` variable matches the option value.<\/li>\n\n\n\n<li>The default value is set to `&#8217;green&#8217;`, so this option is selected when the component initializes.<\/li>\n<\/ul>\n\n\n\n<p><strong>Essential Practices :<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Make sure that the condition bound to the selected property precisely reflects default value.<\/li>\n\n\n\n<li>To avoid multiple default selections, only one option must have the selected property set to true.<\/li>\n<\/ol>\n\n\n\n<p>This method can make the template more verbose, especially with many options. Consider using reactive forms or otherwise ngModel for cleaner code.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-28f84493 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-45c10ec9 wp-block-columns-is-layout-flex\" style=\"margin-top:var(--wp--preset--spacing--60);margin-bottom:var(--wp--preset--spacing--60)\">\n<div class=\"wp-block-column hb-blog-cta hb-cta-blog-new is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:100%\">\n<div class=\"wp-block-group is-nowrap is-layout-flex wp-container-core-group-is-layout-6c531013 wp-block-group-is-layout-flex\">\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\">\n<p class=\"has-text-align-left cta_button_banner has-ast-global-color-5-color has-text-color has-link-color wp-elements-603b3ed5d6c79c519f28efd9a5caba62\" style=\"padding-bottom:var(--wp--preset--spacing--40)\"><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong><strong>Hire Angular Developers Now &amp; Scale Your Apps!<\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/strong><\/p>\n\n\n\n<p class=\"has-ast-global-color-5-color has-text-color has-link-color wp-elements-60e4343c2ac1f7e7327cee915fb1c232\" style=\"padding-bottom:var(--wp--preset--spacing--50)\">Whether it\u2019s forms, UI\/UX, or overall app optimization, our Angular developers can transform your ideas into smooth &amp; responsive applications.
