Setting Dependency For eg. in Google Sheets, to load the list of headers inside a worksheet, the user has to first select a worksheet. Furthermore, to select a worksheet, the user has to select a sheet. There are three config dataslots
  • Select a sheet
  • Select a worksheet
  • Select headers
Let’s look at the example below:
In case of dependent dataslots, the list of options will only load when the value inside the parent dataslot is set. Let’s look at the example of Google Sheets, where value is not set for any of the three dataslots: 
/* The options appear only in the first 
config id because its value is not yet set and 
other config dataslots are dependent on this.
*/
