how to show more than 500 characters of helptooltip for a dropdown?

Question

Have a large "HelpToolTip" text more than 500 characters limit which is a mandatory text for the product type. 
 Please advise how to can we show a large helptooltip on a dropdown? (It cannot take a link field inside the "label" property or buttonwidget inside the "label" to show beside the label of dropdown. 
 How to fix it? 
 Can we show help text for each option in the dropdown list instead when user hover's on to it the help text shows up for each option separately?

If your help tooltip is going to be that long maybe you should try to have it in a separate section at the bottom of your interface, display it in a read only text field and just add in your tooltip some text like "Please refer to Help section for more information". If you need to have all the information in the tooltip you can establish some logic to display a specific text for each option on your dropdown so it will only display the information needed.

Anusha, 
 
Based on my understanding of your question, there is not OOTB way of achieving what you're looking for (have hover over descriptions for each distinct value in a dropdown). There are workarounds you could do to achieve this: 
1. Once the user selects a value in the dropdown, display a side-by-side field with the specific description. This wouldn't give them the ability to view the description real-time when selecting, but would be better than nothing. 
2. You could restructure the design to be a two column selectable grid where the name and description would both display when the user is deciding selection. 
 
Best,
