Form controls like <input>, <select>, <textarea> are the tags used to add custom styles, sizing, focus states to  input field, select item, and text-areas etc. Below are utilities of form control:

  • Sizing: This utility is used to set the label of the form input field in different sizes.
  • Disabled: This attribute is used to give it a grayed-out appearance and remove pointer events.
  • Readonly: This attribute is used to prevent modification of the input’s value.
  • Readonly plain text: Form Controls Readonly plain text is used to create a readonly input field as a plaintext. To create a plain text input field, we will use .form-control-plaintext class. This class removes the styling and preserves the correct margin and padding.
  • File input: This utility is used to browse the file from your computer.
  • Color: Bootstrap 5 Form Control Color is used to set the color in the color type input field. To create a color-type input field, type=”color” attribute is used in <input> element.
  • Datalists: Form controls datalists are used to create a group of options (group of <option> elements) that can be accessed by using an input element. It is similar to the <select> element but the difference is that it has more menu styling limitations and differences.

Example 1: Let's see an example of sizing.
