List widget: two columns

GeoinformationGießen

Hi,

I made a list which is linked to data. This list shows pictures of places, one picture for each place. The pictures which are displayed change depending on the selected area in the map.

Is it possible to build a list with two colums instead of just one? I would like to have the pictures to be shown in two columns.

Thanks!

I'd suggest as the LayerList widget is in fact a <ul> Element to change the CSS of the affected classes.

you can use "Flexbox CSS" (above) or "Floating CSS" (below). I'd go with Flexbox

<SPAN class="comment token">/* define width of column container */</SPAN>
<SPAN class="selector token">.column</SPAN> <SPAN class="punctuation token">{</SPAN>
  <SPAN class="property token">float</SPAN><SPAN class="punctuation token">:</SPAN> left<SPAN class="punctuation token">;</SPAN>
  <SPAN class="property token">width</SPAN><SPAN class="punctuation token">:</SPAN> 50%<SPAN class="punctuation token">;</SPAN>
  <SPAN class="property token">padding</SPAN><SPAN class="punctuation token">:</SPAN> 5px<SPAN class="punctuation token">;</SPAN>
<SPAN class="punctuation token">}</SPAN>

<SPAN class="comment token">/* Clear floats after image containers with after pseudoclass */</SPAN>
<SPAN class="selector token">.row::after</SPAN> <SPAN class="punctuation token">{</SPAN>
  <SPAN class="property token">content</SPAN><SPAN class="punctuation token">:</SPAN> <SPAN class="string token">""</SPAN><SPAN class="punctuation token">;</SPAN>
  <SPAN class="property token">clear</SPAN><SPAN class="punctuation token">:</SPAN> both<SPAN class="punctuation token">;</SPAN>
  <SPAN class="property token">display</SPAN><SPAN class="punctuation token">:</SPAN> table<SPAN class="punctuation token">;</SPAN>
<SPAN class="punctuation token">}</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

Finally substitute the classes row and column with the classes used by esri, look for them by inspecting the element in the browser dev tools => layerlistul.png
