Hi,
Please find the attached patch for the Backgrid *StringDepsCell.*
The *StringDepsCell* displays HTML escaped strings and accepts
anything typed in.
Also, Listen to the dependent fields.
Usage of the Backgrid Cell:
If the Precision cell is dependent on the Datatype then:
{
id: 'precision', label:'{{ _('Precision') }}', type: 'test'
cell: *Backgrid.Extension.StringDepsCell*, deps: ['datatype']
}
Thanks,
Khushboo
