How can I make a push button in a matrix widget no release?
Thanks

The matrix’ props property can be used to override its children’s properties, to enable the norelease mode, you’d set props to:

{
  "norelease": true
}

Multiple properties can be overridden this way, for example:

{
  "norelease": true,
  "on": 100,
  "off": -1
}

Also, formulas in this context are given an extra variable ($) that exposes the subwidget’s index:

{
  "norelease": true,
  "on": 100,
  "off": -1,
  "label": "JS{{return 'btn ' + $}}"
}
