I have a table with my data and I put it in a repeat, that works.
But I would like the design in different rows and columns.
In an older version of dreamweaver I did that with Horizontal Looper.
How do I get this done?

The repeat just repeats your elements, it does not control the direction. The direction of the elements in the repeat (horizontal or vertical) depends entirely of their CSS display property.

block elements are repeated one per row, while inline elements are repeated on one line. You can change the display property of an element using CSS.

Is there no other way? No extension?

No other way - what do you mean? It's as simple as that ... block elements will be repeated one per line, inline and inline-block ones in one line ... i really don't understand what exactly do you expect?

look at www.mspc.be/mastercar/testpagina.php all tables
all tables are listed below each other
but i want it so like on www.mastercar.be/classiccars.php

could I do that with block elements? I don't find anything about it

I don't understand what this layout is supposed to be like. It's 2021 and nobody is using tables for page layouts any longer.
I think you should first create your layout with static content and make it look good, and after that apply the repeat region properties.

no problem, it worked!

thank you very much for the support
