Substring widget: How is the widget is using the JavaScript String substring() functionality in a form?

By the way: I am trying to substring the Autocomplete Widget Field (have to use this as due to performance problems (huge options list) with other list options). Any hint how the widget is using the JavaScript String substring() functionality in a form and if this is possible without the Substring Widget is welcomed.

Unfortunately, I do not know how the Substring widget is working. Can you please explain in more details what exactly are you trying to achieve and maybe we will be able to provide you some workaround. 

If you have a list with a lot of options that you want to add to your form, maybe you use the Dynamic Dropdown widgets. This widget will allow you to sort available options.

Thank you for your answer.

Regarding Dynamic Dropdown unfortunately this is not meeting our users needs due to its not possible to split in groups. The list is reaching the text character value limit of the autocomplete widget field. We try than to reuse a part of the user choice string for further concatenate the substring with another text field. Unfortunately the substring is highly variable so conditions would be almost endless.

 

If anybody of your team knows the technique behind the integration of substring() in a form this would be a nice plus.

I will check with our developers how is the Substring widget is using the JavaScript substring() functionality in a form. 

If we can provide you such info we will inform you via this thread.
