Consistent Styling for Nested Lists with Bootstrap

问题


Is there a way to make nested lists in twitter bootstrap look like a normal list, with the nested items simply indented (and have it work for an arbitrarily deep nesting)? By default, nested lists look like this:

<ul class="list-group">
    <li class="list-group-item">One</li>
    <li class="list-group-item">Two
        <ul class="list-group">
            <li class="list-group-item">Item 2a</li>
            <li class="list-group-item">Item 2b</li>
        </ul>
    </li>
    <li class="list-group-item">Three
        <ul class="list-group">
            <li class="list-group-item">Item 3a</li>
            <li class="list-group-item">Item 3b</li>
        </ul>
    </li>
</ul>

How can I make these nested lists appear like this (or in some similar way):

This was my approach:

    .list-group-collapse li > ul li:first-child {
        border-top-left-radius: 0;
        border-top-right-radius: 0;
    }

    .list-group-collapse li > ul {
        margin-left: -16px;
        margin-right: -16px;
        margin-bottom: -11px;
    }

If you are using BS3, then adding the .list-group-collapse class to your grouped list will do the trick. See JSFiddle: https://jsfiddle.net/oscar_dr/d2wpn8sd/1/

Of course, you could extend BS with this class or change the values to your custom measures if you have a customized Bootstrap.

EDIT: Added snippet to answer:

.list-group-collapse li>ul li:first-child {
  border-top-left-radius: 0;
  border-top-right-radius: 0;
}

.list-group-collapse li>ul {
  margin-left: -16px;
  margin-right: -16px;
  margin-bottom: -11px;
}

I modified Marcos answer to work with Bootstrap 4 (and fort-awesome icons) since glyphicons are no longer part of Bootstrap. The main changes are:

  • replace glyphicons by fort-awesome icons
  • add class list-group-item-action to list-group-item
  • redefine .collapse in css (maybe there is a better approach)

.collapse {
    display: none;
    &.show {
        display: block;
    }
}

Bootstrap 4 Update

I wanted to be able to use this with bootstrap 4. Hope this helps someone else.

Here is the code using font awesome (since glyphicons are not supported in V4).
