Hi Frederick,

Yes, I've attached an example that hides the text input table row when the drop-down has a value == 'export'.

It does this by adding an onchange="" event handler to the dropdown and also an Initialize() function.

It doesn't read them on startup but when it loads it, it stores it in memory so the next run doesn't load it from disk again.

See here for a moi.ini setting which will disable the caching:
