A drop-down list (abbreviated drop-down, or DDL; also known as a drop-down menu, drop menu, pull-down list, picklist) is a graphical control element, similar to a list box, that allows the user to choose one value from a list. When a drop-down list is inactive, it displays a single value.

Set toggle={false} property inside DropdownItem to prevent dropdown from closing.

addEventListener('click', function(event) { event. stopPropagation(); }); Alternatively, you can use event. preventDefault() to prevent the default behavior of the click event, which can also prevent the menu from closing −

Disable/Enable Dropdown with javascript var inputs = document.getElementsByClassName('dropdown-container'); if($parameters.IsActive){ /* Ativa tudo */ inputs.forEach(function(input){ ... var inputs = document. querySelectorAll('input[type="text"], input[type="checkbox"], input[type="number"], input[type="tel"]');

A viable solution is overlaying the other content instead of re-adding the dropdown into the normal flow. put position:absolute on your dropdown content so it doesn't disturb the normal flow.

As it's an element left to the browser to render, no, it's not possible (at least not as far as standards are concerned). Your best option is to use an HTML substitute for the dropdown menu - this can be achieved with CSS and Javascript, though multiple javascript/jQuery libraries alread exist to perform this task.

For sub-menu to not push the content down it needs to have position: absolute style. Other bits of css is to fix the styling and sub-menu width. Make your dropdown menu's position: absolute; and then the element under it as position: relative; .
