Dropdown

Dropdown allows a user to select a value from a series of options

This component is deprecated in v5

It will be replaced by a new component. Please use the custom select component instead.

How it works

Here’s what you need to know before getting started with Dropdown component:

  • It depends on Collapse, Card and List group
  • A hidden input include data when form is submitted
  • Options can be written in HTML format and have two attributes:
    • data-value: value used to hide input
    • data-content (optional): string used to label

Example

A dropdown can be used to select between choices in a form.

  <div class="nj-form-group">
    <div class="nj-dropdown" data-toggle="collapse" data-target="#dropdownSimpleCountry" tabindex="0">
      <input type="hidden">

      <div class="nj-dropdown__list nj-collapse" id="dropdownSimpleCountry">
        <div class="nj-card border">
          <div class="nj-list-group nj-list-group--no-border nj-list-group--sm my-1">
