How can I remove the arrow from drop down list in

问题:

I am trying to remove the arrow that appears on a drop down menu in Twitter Bootstrap framework. Has anyone figured a way of removing the arrows?

回答1:

From: https://getbootstrap.com/2.3.2/components.html#buttonDropdowns

<div class="btn-group">
  <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">
    Action
    <span class="caret"></span>
  </a>
  <ul class="dropdown-menu">
    <!-- dropdown menu links -->
  </ul>
</div>

If you remove <span class="caret"></span> the arrow is not shown.

Tried it using the dev. console in Chrome, and seems to work.

Removing the caret class from the link removes the arrow from the navigation bar,

.dropdown-menu::before, 
.dropdown-menu::after {
    border: none;
    content: none;
}

Will remove the little tab from the drop down menu its self.

If you copy an existing Bootstrap dropdown example, the menu button tag looks something like this:

<button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">Menu Name</button>

Removing the dropdown-toggle class removes the arrow (or caret):

<button class="btn btn-primary" type="button" data-toggle="dropdown">Menu Name</button>

回答4:

Just remove border-bottom from dropdown-menu will remove arrow from the navigation bar.

.navbar .nav > li > .dropdown-menu:before, .navbar .nav > li > .dropdown-menu:after{
    border-bottom: none;
}

回答5:

I've found the best solution is to add overflow:hidden; to .dropdown-menu

回答6:

.dropdown-toggle::after{
    display: none;
}

回答7:

add .dropdown-toggle-split class in the tag

回答8:

The only thing that worked for me was that I removed class="caret" if you are using bootstrap dropdown. Hope this work for you too.

In Bootstrap4 remove "dropdown-toggle" class from "a" element.
