this is an extended question I encountered after my previous question.
The problem lies when someone clicked on the arrow to show the advanced searches, it drops down the form as expected. However, the moment when someone clicked on the select drop down, the whole dropdown menu would then collapse on it's own.
I've been trying to find out what element/trigger is causing this issue and see if there's a way to work around this, but I have no progress at all
Here's what I've observed so far
- [Expected] If the user clicked outside of the drop menu area, the menu collapses
- [Unexpected] If the user clicked any of the whitespace within the drop menu, the menu still collapses
- [Expected] if user clicked on the text field, checkbox, radiobox, textarea, they are supposed to be able to type and enter required texts.
- [Unexpected] If the user clicked a select menu, the dropmenu collapses instantly
I have dropped a sample code down below to demonstrate the question I have.

Reset to default 4Bootstrap Dropdown menus will always close on click, except for when a <form> is used. The way to prevent it from closing on click is to use a <form> element inside dropdown...

Another option is to use the jQuery stopPropagation() method: https://www.codeply./go/4dVvDDpChW
$('.dropdown-menu').click(function(e) {
e.stopPropagation();
});
