[DropDowns] itemDisabled performance optimization

Hi,

The current scenario involves the itemDisabled function being invoked five times for each item when the popup is active.

Example - https://stackblitz.com/edit/angular-natpq9-5uzrh5?file=src%2Fapp%2Fapp.component.ts

It would be preferable to optimize this such that the function is called only once per item.

Following a recent review, we've decided to reopen this request. 

While it has received limited community interest over the years, we believe it addresses a valid scenario and is worth keeping active. 

We encourage everyone interested in this request to vote for it and share additional details about their specific use case to help us better understand its relevance and demand.

Regards,

We are declining this request due to low interest and demand.

However, if there is a surge in popularity at a later time, we will reconsider its status.
