Change height cells tabbar depending on the attached components

Hi,

In a tabbar I use the “Different Content in the Same Cell” feature to display
2 grids
1 tree
3 URL
1 Accordion

that works very well but
To have a complete visualization of the attached URLs, I significantly increased the height of the cell
This does not pose a problem for the grids which have the height that I have defined.
But I can’t do the same with the accordion (single mode)
Or in other words define a height for my accordion to the collapsed items always being visible
However my accordion remains at the useful height for my cells with url attached
Sorry this must be obvious but I can’t find the solution

Thanks for your help
