[Combo Box] Allow expression in field 'source Attribute'
Frontend (App Interfaces)
Platform Server Release Oct.2019 CP1

Many times the value we need to show in the combo box is a combination of several fields :  'code - name', for example.

The combo box only allows the selection of 1 field of the selected Entity/Record.

It would be great if we could "join" several fields of the selected entity/record.

Now we need to make another query, to build a list with the needed structure.

Nice idea, Nelson!

I've already felt that need a few times myself.

Working on it
expected delivery in Q4 2019

Hi Nelson,

That's a great idea. Soon we will be launching the next generation of web applications, reusing several features from mobile and adding a couple of others. One of the things that will be available is the dropown widget, which allows you to do exaclty that.

Hi Nelson,

We are happy to announce that your idea has been implemented and made available with the Oct 02nd release.

Below you will find a short description of the Dropdown Widget capability in Reactive Web Apps, from our "Reactive Web: The Next Generation of Web Apps" forum post.

Native Dropdown widget

The Dropdown Widget has a new property Options Content, which you can set to Text Only or Custom. Text Only gives a native look and feel of the dropdown lists in your reactive web and mobile apps. Set Options Content property to Custom to build a dropdown with a list of images or other widgets.

Thanks again for sharing your idea!


As always, it's a joy to contribute to this great platform!

You've made it even better than my original idea. Great work!
