AdvancedDataGrid Tree Structure

AdvancedDataGrid Query:
1. As shown in the sample image i need to add multiple filter child nodes dynamically.
Here in this case ClusterBy,FilterComponent,AbstractQuestionSpecification,Operator.
2.For the added child nodes i need show delete button so that i can delete that added node dynamically

Refer the sample image.

Thanks for your sol.
Can you redesign my screen according to the below sample image which is my actual requirement.

If you observe in the sample image when we expand clusterby by default it should contain Attributetype form without remove button for it. Next when we click on add button next to cluserby it should add mulitple nodes dynamically with Attributetype and it should contain remove button for those added nodes.And when we click on remove button it should remove that added nodes dynamically.

Simillarly for others also

1.ClusterBym

AttributeType

2.FilterComponent

ClusterAggregateFunction

3.AbstractQuestionSpecification

AttributeType
NodeColourRegex
NavigationStrategyComponentAlias

Below is my current working code.

Thanks,
Alam.

That totally different what you draw on your top picture. Now you don't want to use new rows instead creating a Form as item rendere
Yes, we need to create forms for clusterBy,FilterComponent,AbstractQuestionSpecification etc...as shown in the picture.

Can you provide me the sample code.

Thanks,
Alam.
I spent 3 hours for creating this sample.
Now you're asking to rewrite from begging.
I would liketo get points for my time first. Before starting a new design.
I will appreciate when you will open a new thread please can you attach one more tag "ActionScript"
