puzzle vs. runcode()

Thanks! Where to add ‘exec script’ after setting variables and procedures? Can not find this option in puzzles.
It is a big house and I have 120 collections whose names categorized with ‘AXXX’,’DXXX’,’FXXX’,’TXXX’. I want to add four buttons ‘A’/’D’/’F’/’T’ to show or hide the corresponding collections. Can this be done by puzzle?

Thanks for that! Also how to add button and listener in runCode(). Any examples available?

// utility function envoked by almost all V3D-specific puzzles
// retrieve all objects on the scene
function getAllObjectNames() {
var objNameList = [];
appInstance.scene.traverse(function(obj) {
if (notIgnoredObj(obj))
objNameList.push(obj.name)
});
return objNameList;
}
This is the code script for getAllObjectNames().
Is there a function which can getAllGroups() in puzzle?

Thanks it works but get group name retrieved by objects and then removed the repeated groups in the group list. It is a bit time consuming and if there is a better way to retrieve the group list from scene, will be better.
