If anyone would kindly tell any ways that I can get user location who fill into Form that is made from Data Table would be great. Like a widget that will automatically get user current coordinate (after user accept permission of course).
@frederikdc @cwinhall do you have any thoughts on this? 
The only way you can get the location of the user is through a piece of JavaScript. You can implement this in an IFrame element in the app builder. The city tours application template (City Tours) uses this approach to add a pinpoint to a map.
However, I don’t see a way how you can store this value inside your database. Except for the creation of a plugin, but that requires a lot of development work.
i mean getting longitude and latitude of the locations. I think we can put those into database as simple decimal
Yes, you can store it as a decimal, but I don’t see a way on how you can insert the longitude and latitude automatically in the database through a form.
