Activity Pickers (3.7-preview)

Overview

This section explains how to change the activity picker used in the workflow editor. Currently, two activity picker types are supported: Accordion (default) and Treeview.

Accordion

To use the Accordion activity picker, use the following line.

builder.Services.AddScoped<IActivityPickerComponentProvider, AccordionActivityPickerComponentProvider>();

Accordion Example

When using nested activity categories, the accordion picker defaults to returning the first category within the string. You are able to change this behaviour by specifying your own CategoryDisplayResolver.

builder.Services.AddScoped<IActivityPickerComponentProvider>(sp => new AccordionActivityPickerComponentProvider
{
    // Example - Replace the default category resolver with a custom one.
    CategoryDisplayResolver = category => category.Split('/').Last().Trim()
});

Treeview

To use the TreeView activity picker, add the following line.

builder.Services.AddScoped<IActivityPickerComponentProvider, TreeviewActivityPickerComponentProvider>();
