Tree view is getting wrapped

Question

The tree view is getting wrapped when you resize the window.

In Bootstrap, the table does not shrink on window resize but a horizontal scroll bar becomes visible which can be used to scroll the table to see it.

How can it be made like the Bootstrap 4 responsive table? So that on window resize the tree view does not shrink and a horizontal scroll bar becomes visible to scroll and view the full tree view.

 /*Now the CSS*/ * {margin: 0; padding: 0;} .tree ul { padding-top: 20px; position: relative; transition: all 0.5s; -webkit-tranasition: all 0.5s; -moz-transition: all 0.5s; } .tree li { float: left; text-align: center; list-style-type: none; position: relative; padding: 20px 5px 0 5px; transition: all 0.5s; -webkit-transition: all 0.5s; -moz-transition: all 0.5s; } /*We will use ::before and ::after to draw the connectors*/ .tree li::before, .tree li::after{ content: ''; position: absolute; top: 0; right: 50%; border-top: 1px solid #ccc; width: 50%; height: 20px; } .tree li::after{ right: auto; left: 50%; border-left: 1px solid #ccc; } /*We need to remove left-right connectors from elements without any siblings*/ .tree li:only-child::after, .tree li:only-child::before { display: none; } /*Remove space from the top of single children*/ .tree li:only-child{ padding-top: 0;} /*Remove left connector from first child and right connector from last child*/ .tree li:first-child::before, .tree li:last-child::after{ border: 0 none; } /*Adding back the vertical connector to the last nodes*/ .tree li:last-child::before{ border-right: 1px solid #ccc; border-radius: 0 5px 0 0; -webkit-border-radius: 0 5px 0 0; -moz-border-radius: 0 5px 0 0; } .tree li:first-child::after{ border-radius: 5px 0 0 0; -webkit-border-radius: 5px 0 0 0; -moz-border-radius: 5px 0 0 0; } /*Time to add downward connectors from parents*/ .tree ul ul::before{ content: ''; position: absolute; top: 0; left: 50%; border-left: 1px solid #ccc; width: 0; height: 20px; } .tree li a{ border: 1px solid #ccc; padding: 5px 10px; text-decoration: none; color: #666; font-family: arial, verdana, tahoma; font-size: 11px; display: inline-block; border-radius: 5px; -webkit-border-radius: 5px; -moz-border-radius: 5px; transition: all 0.5s; -webkit-transition: all 0.5s; -moz-transition: all 0.5s; } /*Time for some hover effects*/ /*We will apply the hover effect the the lineage of the element also*/ .tree li a:hover, .tree li a:hover+ul li a { background: #c8e4f8; color: #000; border: 1px solid #94a0b4; } /*Connector styles on hover*/ .tree li a:hover+ul li::after, .tree li a:hover+ul li::before, .tree li a:hover+ul::before, .tree li a:hover+ul ul::before{ border-color: #94a0b4; }

Answer 1

As a quick example, I added a container around the .tree element, and gave it a width: 100% and overflow: scroll . Then I set .tree to have a static width. Seems to work fine.

 /*Now the CSS*/ * {margin: 0; padding: 0;} .tree { width: 1000px; } /* ******* I added this ******* */ .tree ul { padding-top: 20px; position: relative; transition: all 0.5s; -webkit-tranasition: all 0.5s; -moz-transition: all 0.5s; } .tree li { float: left; text-align: center; list-style-type: none; position: relative; padding: 20px 5px 0 5px; transition: all 0.5s; -webkit-transition: all 0.5s; -moz-transition: all 0.5s; } /*We will use ::before and ::after to draw the connectors*/ .tree li::before, .tree li::after{ content: ''; position: absolute; top: 0; right: 50%; border-top: 1px solid #ccc; width: 50%; height: 20px; } .tree li::after{ right: auto; left: 50%; border-left: 1px solid #ccc; } /*We need to remove left-right connectors from elements without any siblings*/ .tree li:only-child::after, .tree li:only-child::before { display: none; } /*Remove space from the top of single children*/ .tree li:only-child{ padding-top: 0;} /*Remove left connector from first child and right connector from last child*/ .tree li:first-child::before, .tree li:last-child::after{ border: 0 none; } /*Adding back the vertical connector to the last nodes*/ .tree li:last-child::before{ border-right: 1px solid #ccc; border-radius: 0 5px 0 0; -webkit-border-radius: 0 5px 0 0; -moz-border-radius: 0 5px 0 0; } .tree li:first-child::after{ border-radius: 5px 0 0 0; -webkit-border-radius: 5px 0 0 0; -moz-border-radius: 5px 0 0 0; } /*Time to add downward connectors from parents*/ .tree ul ul::before{ content: ''; position: absolute; top: 0; left: 50%; border-left: 1px solid #ccc; width: 0; height: 20px; } .tree li a{ border: 1px solid #ccc; padding: 5px 10px; text-decoration: none; color: #666; font-family: arial, verdana, tahoma; font-size: 11px; display: inline-block; border-radius: 5px; -webkit-border-radius: 5px; -moz-border-radius: 5px; transition: all 0.5s; -webkit-transition: all 0.5s; -moz-transition: all 0.5s; } /*Time for some hover effects*/ /*We will apply the hover effect the the lineage of the element also*/ .tree li a:hover, .tree li a:hover+ul li a { background: #c8e4f8; color: #000; border: 1px solid #94a0b4; } /*Connector styles on hover*/ .tree li a:hover+ul li::after, .tree li a:hover+ul li::before, .tree li a:hover+ul::before, .tree li a:hover+ul ul::before{ border-color: #94a0b4; } .tree-cont { width: 100%; overflow: scroll; }

 <div class="tree-cont"> <!-- added this wrapper --> <div class="tree"> <ul> <li> <a href="#">1</a> <ul> <li> <a href="#">2</a> <ul> <li> <a href="#">2.1</a> </li> <li> <a href="#">2.2</a> </li> </ul> </li> <li> <a href="#">2</a> <ul> <li> <a href="#">2.1</a> </li> <li> <a href="#">2.2</a> </li> </ul> </li> <li> <a href="#">2</a> <ul> <li> <a href="#">2.1</a> </li> <li> <a href="#">2.2</a> </li> </ul> </li> <li> <a href="#">2</a> <ul> <li> <a href="#">2.1</a> </li> <li> <a href="#">2.2</a> </li> </ul> </li><li> <a href="#">2</a> <ul> <li> <a href="#">2.1</a> </li> <li> <a href="#">2.2</a> </li> </ul> </li> <li> <a href="#">2</a> <ul> <li> <a href="#">2.1</a> </li> <li> <a href="#">2.2</a> </li> </ul> </li> <li> <a href="#">3</a> <ul> <ul> <li> <a href="#">3.1</a> <ul> <li> <a href="#">3.1.1</a> </li> <li> <a href="#">3.1.2</a> </li> </ul> </li> <li> <a href="#">3.2</a> </li> </ul> </ul> </li> </ul> </li> </ul> </div> </div>
