Bootstrap Dropdowns
Bootstrap Dropdowns
Bootstrap Dropdowns are a versatile component that allows you to create dropdown menus with various options, such as links, buttons, or forms. Dropdowns are useful for organizing and displaying content in a structured and easily accessible format.
To create a basic dropdown in Bootstrap, you can use the <div> element with the class dropdown, along with a button or link to trigger the dropdown. Here is an example:
<div class="dropdown">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-bs-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown button
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenuButton">
<li><a class="dropdown-item" href="#">Item 1</a></li>
<li><a class="dropdown-item" href="#">Item 2</a></li>
<li><a class="dropdown-item" href="#">Item 3</a></li>
</ul>
</div>
This will create a dropdown with a button that, when clicked, will display a menu with three items. You can customize the appearance of the dropdown by using additional classes, such as dropdown-menu-right to align the dropdown menu to the right of the button.
Bootstrap also provides a number of helper classes to make it easier to create more complex dropdowns. For example, you can use the dropdown-header class to add headers to the dropdown menu, or the dropdown-divider class to add dividers between the menu items.
<div class="dropdown">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-bs-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown button
</button>
<ul class="dropdown-menu" aria-labelledby="dropdownMenuButton">
<li class="dropdown-header">Header 1</li>
<li><a class="dropdown-item" href="#">Item 1</a></li>
<li><a class="dropdown-item" href="#">Item 2</a></li>
<li class="dropdown-divider"></li>
<li class="dropdown-header">Header 2</li>
<li><a class="dropdown-item" href="#">Item 3</a></li>
</ul>
</div>
This will create a more complex dropdown with two headers, dividers, and four menu items.
Overall, Bootstrap Dropdowns are a powerful tool for organizing and displaying content in a structured and easily accessible format. They are highly customizable and can be used in a variety of contexts, such as navigation menus or form inputs.
