Input Types
Most common form control, text-based input fields. Includes support for all HTML5 types: text, password, datetime, datetime-local, date, month, time, week, number, email, url, search, tel, and color.
Select menu
Custom <select> menus need only a custom class, .form-select to trigger the custom styles.
Switches
A switch has the markup of a custom checkbox but uses the .form-switch class to render a toggle switch. Switches also support the disabled attribute.
Checkboxes and radios
Floating labels
Wrap a pair of <input class="form-control"> and <label> elements in .form-floating to enable floating labels with Bootstrap’s textual form fields. A placeholder is required on each <input> as our method of CSS-only floating labels uses the :placeholder-shown pseudo-element. Also note that the <input> must come first so we can utilize a sibling selector (e.g., ~).
Floating Example
Selects
Input Sizes
Set heights using classes like .input-lg, and set widths using grid column classes like .col-lg-*.
Input Group
Easily extend form controls by adding text, buttons, or button groups on either side of textual inputs, custom selects, and custom file inputs
Basic Example
Horizontal form
Column sizing
As shown in the previous examples, our grid system allows you to place any number of .cols within a .row.
Auto-sizing
Gutters
