Custom homepage design like this website

Hi there,

you can use the GenerateBlocks plugin:

1. Add a GB Grid block with 3 columns:

Note each column has a Container Block inside it that you can add a border and other styles to:

2. Inside each Grid column container add a GB Query Loop block:

Select the Query Loop block, and in its sidebar settings you can Add Parameter.
Choose: Taxonomy
And then select Category followed by the Term you want displayed.

Repeat for each query loop
