Sitecore Custom Field – Image Coordinate Picker

Someone wants you to develop a Sitecore custom field which allows for the users to pick the image coordinate inside Sitecore. The main purpose is to render the hot spots correctly on Hero Image / Banner Image as are the ones are defined inside Sitecore.

Assumptions:

  • based on GOOGLE MAP LOCATION PICKER FIELD
  • the hot spot items are created as sub-items of Hero / Banner items
  • there is a Sitecore Image field for Hero Image / Banner Image in Hero / Banner item

If that is the case, you may try to play with my Image Coordinate Picker field.

How to install it

Download this tool as a Sitecore package on Sitecore Marketplace or on Gitlab then install it to your Sitecore instance via Installation Wizard.

Update (04-August-2017): a new version 1.1 is to make it work properly in case there is more than 01 Image Coordinate Picker field on a template.

  • the known issue: if you click on any Pick Coordinate link, there will be 03 different dialogs are displayed: one of Location 1, one of Location 2 and one of Location 3 . The root cause is that version 1.0 does not restrict the current control of a specific Pick Coordinate link (the reference)
