How can I split a catalog item form into 3 columns evenly?

[Apex Predator]

I have a catalog item with multiple variables.

I have used Container start and container split multiple times to get a view something like this,
But this is uneven with the first column occupying 50% of the form width.
Is there a way I can split these evenly?
I tried setting the variable width(Problem Category) to 25% but it did not change anything. It shows the following message inside the variable.

Here you go

It should look like this

You have to carefully place the container start, container end and also the splits. Also ensure you have the right layout on the container start, in the example i have used two sides, one side , then other side.

Sounds good. I will look for an alternative design. Thanks!

You may need to change the variable width for all those fields on the first column. Please let me know if this will work.

This will only work for a single column. Check the second part of my question for more information.
