We are also facing same problem as mention in https://www.flexmonster.com/question/height-of-fields-popup-need-to-be-adjusted/
Did you added any support in recent upgrades? Or Can you please suggest any workaround other than pre-defining its height by using CSS.
Thank you for reaching out to us.
Our team wants to inform you that no updates were made on this point.
We will let you know in case something is changed.
Also, no other workaround than CSS overwriting is known at the moment.
Do not hesitate to contact us in case other questions occur.
We are pleased to inform you that now it is possible to resize the Field List vertically to fill the entire height of the grid container.
This is available in the 2.8.21 version of Flexmonster: https://www.flexmonster.com/release-notes/.
You are welcome to update the component: https://www.flexmonster.com/doc/updating-to-the-latest-version/.
Please let us know if everything works.
We are wondering whether the recently introduced feature with the Field List resizing works well for you.
Our team is looking forward to hearing your feedback.
