子ul下拉列表因其父高而被截断

Question

 <div class="carousel-inner">
   ...
   <ul class="dropdown-menu">
    <li>...</li>
    <li>...</li>
    <li>...</li>
    <li>...</li>
   </ul>
</div>

I have 4 elments in div tag but only 2 are shown. How can I increase it's height show all dropdown items.

I have used overflow:auto; but this is adding scroll to entire parent element which is not looking good. Also padding-bottom also works here but it extends parent's background behind the dropdwn which is not needed.

fuelux .dropdown-menu {
  position: absolute;
  top: 100%;
  left: 0;
  z-index: 1000;
  width: 23%;
  min-width: 50px;
  display: block;

}

 .fuelux .carousel-inner {
   position: relative;
   width: 100%;
   overflow: hidden;
   line-height: 1;
 }

I am also facing the same problem until few minutes ago and below is what solved my issue.

style="min-height:300px;max-height:100%;"

You need to set the min-height of parent div to expanded child menu height size so that the child menu will be displayed with out cutting off by the parent height.

We are setting max-height so that CSS won't consider min-height as the default fixed height of the component. so that it will expand if you are using any Dynamic loading content like GroupBoxes, Choosen boxes with long list, etc.,.

   <div class="carousel-inner" style="min-height:300px;max-height:100%;">
   ...
   <ul class="dropdown-menu">
    <li>...</li>
    <li>...</li>
    <li>...</li>
    <li>...</li>
   </ul>
</div>

Note : For the Menu i am loading 300px is the maximum height required to load complete child menu. Check your height of expanded menu size and change it with min-height value to get desired result.

Answer 2

Are you setting the height to the div-wrapper?

If yes, drop the height out of the stylesheet and the height is automatically set by the content inside the div-wrapper.

For example:

Style:

div {
width: 200px; float: left;
}

ul li {
height: 20px; width: 200px; float: left;
}

when you have 4 elements inside ul, the height of die div-wrapper will be 80px.

I hope i can help you ;)
