Auto Layout with different column width

Hi, I am trying to create responsive columns layout with autolayout feature. It is working with equal width but not worth with a different width. I am able to set fill-container for one but not the other column. I assume, we don’t have full flexbox, with max-width or %. or am i missing something here?

With the new update, layout is slightly changed and i also tried using two different frames with each sizes but that gives a similar result with only one column being responsive.

can’t upload the screenshot, as it is restricted for new user.

Thank you.

Sorry I don’t have a solution for you, but I would also like this as a feature. Almost all of our site components are determined by column width, and they are almost universally unequal within a row.

Ok, Uploading the screenshot now, wonder if we get auto width, max-width or % feature.
