What are Drag Types and Drop Targets?

Drag and drop actions allow users to click and drag an item from location to another within a screen. This allows users to intuitively interact with content, rearrange items, and trigger further actions by dropping onto a designated area. Some examples of drag and drop actions are:

• Dragging a record from a grid onto a delete area to remove it
• Dragging a contact from a grid onto a specific company on a company table to move that contact to that company
• Dragging items into different sections on a Kanban board to change the state of the record - see Making Kanban Boards

How are Drag Types and Drop Targets Configured?

To set up drag and drop on components, a 

Insert excerpt
_drag_type _drag_type nopanel true

 on the object you are dragging from and a 

Insert excerpt
_drop_target _drop_target nopanel true

 on the object you are dropping onto is required. Components that can have 

Insert excerpt
_drag_type _drag_type nopanel true

are:

• grids
• cards

Any component which has an

Insert excerpt
_property_tabs _property_tabs name action nopanel true

 can be a Drop Target. The Drop Action (performed when the drop occurs) is configured in an Actionflow on the Drop Target.

For example, to assign a new company to an employee, a user creates two grids on a screen. The employee and company table have a relationship and are linked by a CompanyIDfield. The employee can be dragged and dropped onto a company to update CompanyID attribute for the employee.

s are set on components on a screen.

Creating a Drag Type

1. Right-click on the grid and select

   Insert excerpt
   _view_show_config _view_show_config nopanel true

    on the component from which data will be dragged

2. On the

   Insert excerpt
   _property_tabs _property_tabs name action nopanel true

   , in the Action Settings section, under Drag Type, select or create a drag type, e.g. Move Contact

3. If creating a Drag Type, click the

   Insert excerpt
   _add_icon _add_icon nopanel true

    button
   1. Name: Enter a name for the drag type
   2. Attributes: create the attributes to be used in the Actionflow, e.g. CompanyID

   3. Insert excerpt
      _finish _finish nopanel true

4. A Drag Mappings section will become available in the Action Settings
5. Click the 

   Insert excerpt
   _mappings_configure _mappings_configure nopanel true

    button
6. Map across attributes from the table onto the 

   Insert excerpt
   _drag_type _drag_type nopanel true

   attributes set above, to be used within the Actionflow

Components with a drag type can be dragged and dropped onto any component which has a drop target with a matching drag type.

Creating a Drop Target

1. Click on the component where data will be dropped to open the

   Insert excerpt
   _property_settings _property_settings nopanel true

2. On the

   Insert excerpt
   _property_tabs _property_tabs name action nopanel true

   , in the Drop Targets section, select or create a drop target, e.g. Add Contact
3. If creating a Drop Target, click the

   Insert excerpt
   _add_icon _add_icon nopanel true

    button
   1. Name: Enter a name for the drop target
   2. Drag Type: Select the drag type (e.g. Move Contact) that matches the drag type set on the component being dragged
   3. Drop Action: Select

      Insert excerpt
      _actionflow _actionflow nopanel true

   4. Actionflow: Select or create an Actionflow to run when a component with a matching drag type is dropped onto this component

   5. Insert excerpt
      _finish _finish nopanel true

        
4. If creating an 

   Insert excerpt
   _actionflow _actionflow nopanel true

   , select the

   Insert excerpt
   _drag_type _drag_type nopanel true

   as the an

   Insert excerpt
   _input _input nopanel true

5. Map in the attribute(s) created on the 

   Insert excerpt
   _drag_type _drag_type nopanel true

6. Then configure your Actionflow as required, e.g. delete a record, move that contact to a company, change the state of the record, etc.

Drag Types and Drop Targets

Worked Examples

Here's a worked example using the Company Data (available from the Learning Centre).

In this example, we are using:  

• A Company Approval Review screen containing:
  • a grid backed by the Companies table
    • with a Background Filter to only companies where their Status does not equal Approved or Rejected
  • two areas containing Approve and Reject icons  - this screen was created using the Multi-Tile  template

Tip
If you are completing this chapter as part of the Actionflow course and using a training instance, the data and screens have already been pre-loaded into the Actionflow Advanced Application. For this example, we'll be working on the Company Approval Review screen.

Example 1: Approve Company Using Drag and Drop

In this example, we'll configure company records on a grid to be draggable, and set up an area on a screen as a drop target to receive the record(s). When a company is dropped in the area, its Status will be updated to Approved. We'll add some additional processing to our Actionflow to update the audit details on the record, showing who made the change, along with the date and time.

Drag Type Setup

1. Open the Company Approval Review screen
2. Right-click on the Companies Pending Review grid and select
