Here is a jinja2 kanban template matching the functionality of a current TAL one.

Did the conversion with deepwiki and then fixed a few issues.

  batch() needed to be called
  change ".is_open()" top ".is_open() is not none" as returned value of "" is false but should be true
  add <span>...</span> around each card label/value
  replace getprop() with i[column_prop] as getprop not defined.

One odd thing is that the lengths of the collapsed columns changes randomly
in Firefox. I assume it's some interaction between the bootstrap CSS and my css.

But I am not able to figure out what's going on.
