sonirathore01 opened a new issue #15532:
URL: https://github.com/apache/echarts/issues/15532


   ### What problem does this feature solve?
   
    ```
   -- I'm using echarts with angular technology here is my version details :
       ngx-echarts: 4.2.2
       echarts: 4.4.0
   ```
   ```
   -- Requirements of feature : 
   ```
    --  I'm trying to implement a tree chart with a formatter function and rich APIs. 
         I need to implement the feature to display selected node details next to the 
         chart so we can see all details related to that selected node and perform any
         other actions like add edit, delete.
   
    -- I need to implement this functionality on the click event of node and I have to highlight that selected node and I’ve used 
       ‘chartClick’ event to catch the click event and for highlighting the node I’m using `rich` APis from echarts.
   
    -- I’m using the expand and collapse feature to expand and collapse the node. Now, the problem is I’m using the click event to select 
         the node, and at the same time Expand and collapse action is also happening, and that is the problem because when the user will 
         click to the node to select it at the same time node will perform expand and collapse action if a node has any child. So, it's a bad 
         user experience.
   
   --  My requirement is to perform an expand and collapse action on `Double click` instead of single click so when a user would like to 
        expand and collapse the node then they will click double click instead of ‘single click’ on the node.
   
   --  The default behaviour of expand and collapse happens on click event and it accepts only boolean values. I’ve checked the 
        documentation and at lots of other places to change its event to double click instead of single click but I was not able to find any 
        solution.
   
   --  So, I just want to have support to configure the trigger event of expand collapse action on a double click event instead of a single 
        click.
   
    Here is the link to a small demo to understand my requirements https://codepen.io/sonirathore01/pen/xxdBPZw.
   
    
   
   ### What does the proposed API look like?
   **expandAndCollapse should have option to configure trigger event as follow **
   ``` 
   chart.setOption({
       series: [
           {
                name: "Hierarchy",
                type: "tree",
                expandAndCollapse: {
                triggerOn: "doubleClick",
                }]
         }```
