We are trying to show the tree structure in the combo box using the following source
https://fiddle.sencha.com/#fiddle/g50&view/editor
We are able to view the tree structure in the combo box however when we select any node its not being displayed in the combo box.
There is a treepicker component available in ExtJS 4 and ExtJS 6. From the fiddle you have provided, I can see that you use ExtJS version 5, but I could not find any reference to the treepicker in the API Docs for this version. You can sneak peek into the version 4 and 6 implementation.
But basically, you just missed setting an event listener on the tree panel picker that will update the value of the field: https://fiddle.sencha.com/#fiddle/2qt0&view/editor

We have created a directive to do a validation of the input/ selected item must be exists in the combo box list. However, it's not working anymore after upgraded the package to 0.18.1 and implement the [allowCustom]="true". It was working in the previous version 0.10.x.
The scenario is when user remove the entry from the combobox and enter a value again, the directive is triggered. But if user, append the content in the combobox, the directive is not triggered at all.
Please help. Video attached

This seems to be a bug in the #progress/kendo-angular-dropdowns#0.18.x release.
I updated the demo to the latest official (0.21.x) and it seems fixed:

How to show combobox in Extjs grid panel using extjs 6.0.1
I saw widget column example but it is rendering combobox only when user clicks on a cell. How to show combobox by default?
Can someone provide a sample in fiddle?
Use the widgetcolumn:
A widget column is configured with a widget config object which
specifies an xtype to indicate which type of Widget or Component
belongs in the cells of this column.

I have an Ext JS 5.0.1 application that I am working on. I have a simple window with a grid and a form. I have the grid bound to my store and when a row is selected, all the textfields in the form bind, but I also have a combobox with its own store. When I select the grid row, I could not get the combobox to bind. I finally figured that out, but now if you change the combobox on the form the grid column just shows object.object. I have created a fiddle if anybody can help me out a little with this problem. Obviously I am trying to use the MVVM but also I would like for it to work in Architect if possible.
Fiddle
Bind value, not selection:
value: '{allPeople.selection.gender}'

Please point me to an Ext JS 4 code sample of a grid with records editable via a popup form. It seems to be a common use case, but I can only find editable grids with editing in place.
My approach:
Each row in the grid has an Edit button, which shows Ext.window.Window with an item Ext.form.Panel.
When the form is submitted I have all the fields, which correspond to a record in the grid store.
I get record using:
var storeRecord = grid.getStore().getAt(index);
But when I modify properties of this record, and hide the form window, the grid does not show updated values.
Am I missing some step? Do I need to force refresh? Or maybe there is a standard way to configure the grid with an editor as a form panel?
After two days of searches, trials and errors, I found the solution:
grid.getView().refresh();
I wish there was a faster way for Ext learning curve. :(
I m new to ExtJs. I was wondering if there's some way wherein i can display multi-line combo-box in ExtJS in a way that for eg : when i select one item, that item may contain 2 values i.e ID and Name., and both the items are considered as one selection, and not with Ctrl+Select way.
Sure there is. Look at the tpl config option of ExtJS ComboBox. You can define a custom template where you may utilize any fields from the Store of the ComboBox as you wish. (See the example included for the tpl config option from ExtJS API documentation that I linked.)
