Bootstrap 5.3 does not include a built-in checkbox-style multiselect dropdown. Its .form-select class styles a native single-select control; a searchable, grouped, or tag-based multiselect needs a custom interface. Colorlib’s 2026 collection presents 20 dropdown patterns plus four other ways to choose multiple items, built with HTML, CSS, and vanilla JavaScript rather than jQuery, Bootstrap files, or a multiselect plugin. See the Colorlib examples.
How to choose a multiselect pattern
Start with the job the control must do, not its appearance. The most useful distinctions are list size, category structure, search needs, selection limits, and how much of the current selection should remain visible.
| Need | Patterns in the collection | Best fit |
|---|---|---|
| A short list with straightforward choices | Multiselect V01: checkbox list with select all; topic tiles; filter checkbox groups; feature checkboxes | Roughly seven choices or fewer, where users can scan without searching. |
| Review or remove a modest selection | V02 and V19: removable selected tags | When seeing each chosen value helps users confirm or revise their choices. |
| Find items in a longer list | V10–V13 and V20: live-search dropdowns | When scrolling through all options would be slow. |
| Make a long list easier to scan | V08 and V18: grouped choices; jump-to-letter behavior | When categories or alphabetical navigation give users a useful route through many choices. |
| Keep a compact summary or constrain choices | V14–V16: country/state lists and compact summaries; V17–V18: selection limits | When the interface must show many possible locations compactly or enforce a maximum number of selections. |
| Show availability across options | Availability grid | When choices make more sense as a grid than as a conventional dropdown. |
These are interaction choices, not interchangeable skins. For a small set, a checkbox list or tiles keep options in view. For a larger set, live search reduces the need to browse by scrolling. Grouping helps when categories are meaningful; a count can keep the closed control compact when users may select many items, while tags make individual selections easier to inspect and remove. Colorlib’s collection identifies these patterns and their example numbers.

No built-in Bootstrap 5.3 control provides the custom checkbox, search, tag, or grouped-dropdown behavior described here. Bootstrap’s Select documentation says, “Custom <select> menus need only a custom class, .form-select to trigger the custom styles.” The class styles the native select, but browser limitations prevent those custom styles from changing its <option> elements. For a different interaction, add a custom interface or use another control pattern. Bootstrap v5.3 Select documentation.

Do these examples need jQuery, Bootstrap files, or a plugin?
Colorlib describes its examples as plain HTML, CSS, and vanilla JavaScript; its article says they do not load jQuery, Bootstrap files, or a multiselect plugin. This is useful if you want a pattern without adding those dependencies, but it does not make every interaction native or accessible automatically. The custom widget still needs implementation and testing suited to your page and users. Colorlib’s example collection.
How should a custom dropdown preserve form values?
Colorlib says its 20 dropdown examples keep a real <select> underneath the custom interface and write selected items back to it. This lets the interface present a different interaction while retaining a form field for submission. The collection’s description is the basis for this behavior; it is not an independent test of every snippet or every integration.
For a select element referenced as select, the collection gives this JavaScript expression for reading selected values:
Array.from(select.selectedOptions).map(o => o.value)For PHP form handling, it notes that a name such as topics[] can receive an array. Confirm that the field name, selected option values, and server-side handling match your application before relying on submitted data. Colorlib’s implementation notes.

How to check keyboard, screen-reader, and mobile behavior
A custom dropdown should be evaluated as an interactive control, not just a visual replica of a select. Colorlib recommends checking the keyboard sequence of opening the list, moving through options with arrow keys, toggling an option with Space, and closing with Escape. Check that focus remains visible and that assistive technology can identify the control and its options; the article’s suggested sequence is guidance, not a claim that every example passes an accessibility audit. Colorlib’s accessibility guidance.
Also try the target device and input method. Native <select multiple> interactions on desktop can require Ctrl-click or Cmd-click, while a custom widget must provide usable touch targets on phones. Test the actual widget in the browsers and assistive technologies relevant to your audience. For the native element’s general behavior, see MDN’s <select> reference.
When should a multiselect impose a limit?
Use a selection cap only when the application has a real constraint, and tell users about it before they reach the limit. The collection includes a seven-choice cap and per-group limits. Put the maximum in the field label or nearby instructions, and ensure the interface explains why another choice cannot be made. A hidden cap feels like a malfunction; a stated cap is a usable constraint. Colorlib’s examples.
