1. We need to change the subsection output in the style settings.
Appearance - Style settings - List of sites / forums, select the item: Display the list of sub-forums under the node
2. Use the extra.less template for output to the bar.
To output in two columns:
Code:
.node .node-subNodeFlatList li {
float: left;
margin: 2px 0 2px 2%;
width: 45%;
}
To output in three columns:
Code:
.node .node-subNodeFlatList li {
float: left;
margin: 2px 0 2px 2%;
width: 31%;
}
