I need to disable some element from the list in the dropdown based on logic

[developer1]

Provide a demo where I can disable of selection of item from dropdown based on the logic

For your reference screenshot attached,

We are facing the issue to setup the item in dropdown list.

We have two requirements,
1)   Need to disable some item for selection
2)   Need some extra space in the item hierarchy-wise

1. option can be disabled dynamically by adding pq_disabled: true property

Please check editor.options callback in this example https://paramquery.com/pro/demos/editors_conditional

2. leading space can be added by adding   in the option text.
e.g., { "value": "SE", "text": " Speedy Express" }
