How to create a Simple dropdown with Tailwind CSS?

To create a Simple dropdown with Tailwind CSS, follow the steps below:

  1. Create a select element with options.
<select class="block w-full rounded-md bg-gray-100 border-transparent focus:border-gray-500 focus:bg-white focus:ring-0">
  <option>Option 1</option>
  <option>Option 2</option>
  <option>Option 3</option>
</select>
  1. Add the Tailwind CSS classes to style the select element.
<select class="block w-full rounded-md bg-gray-100 border-transparent focus:border-gray-500 focus:bg-white focus:ring-0">
  • The block class makes the select element a block-level element.
  • The w-full class makes the select element take up the full width of the container.
  • The rounded-md class adds rounded corners to the select element.
  • The bg-gray-100 class sets the background color of the select element to gray.
  • The border-transparent class removes the border of the select element.
  • The focus:border-gray-500 class sets the border color of the select element to gray when it is in focus.
  • The focus:bg-white class sets the background color of the select element to white when it is in focus.
  • The focus:ring-0 class removes the focus ring from the select element.
  1. Add the Tailwind CSS classes to style the options.
<option class="py-2">Option 1</option>
<option class="py-2">Option 2</option>
<option class="py-2">Option 3</option>
  • The py-2 class adds padding to the top and bottom of the options.
  1. Add the Tailwind CSS classes to style the dropdown arrow.
<svg class="absolute pointer-events-none top-0 right-0 w-5 h-5 text-gray-400 fill-current" viewBox="0 0 20 20">
  <path d="M10 12l-5-5h10z"></path>
</svg>
  • The absolute class positions the arrow element absolutely within the container.
  • The pointer-events-none class makes the arrow element non-clickable.
  • The top-0 and right-0 classes position the arrow element at the top right corner of the container.
  • The w-5 and h-5 classes set the width and height of the arrow element to 5 pixels.
  • The text-gray-400 class sets the color of the arrow element to gray.
  • The fill-current class fills the arrow element with the current text color.
  1. Add the Tailwind CSS classes to style the dropdown when it is open.
<select class="block w-full rounded-md bg-gray-100 border-transparent focus:border-gray-500 focus:bg-white focus:ring-0 appearance-none">
  <option class="py-2">Option 1</option>
  <option class="py-2">Option 2</option>
  <option class="py-2">Option 3</option>
</select>
  • The appearance-none class removes the default appearance of the select element.
  • The appearance-none class is used to remove the default appearance of the select element when it is open.
