How to create layout (Merge two Columns into One)?

Sivaguru_M · June 10, 2022, 3:43pm

In the attached design I have created three columns in the container but I don’t know how to merge the columns into single column in only second row.

Nested columns aren’t supported, unfortunately. However, I see on GitHub that an update to allow one level of nesting was just merged so maybe this will be possible very, very soon.

Add support for columns inside columns (1 level of nesting)
