Hello,

Here are a few questions about Row Groups in a datatable
  • Is there a function to expand / collapse all subheader groups?
  • On top of the button class="p-row-toggler" could the subheader value also be clickable ?
  • Could I set some Rowgroups to be expanded by default?
Thanks in advance.

Hello,
  • According to above question there is no top 'p-row-toggler'
  • And yes, you could set default expanded rows with using 'expandedRows' property

Thanks for your reply but I think there is a mis understanding here.
The questions above are about the Expandable Row Groups with subheaders, like documented here :
https://www.primefaces.org/primevue/sho ... e/rowgroup

any method to handle this? Thanks

Hi,

Yes, it is possible. For example https://codesandbox.io/s/rowgroup-expand-h6egy

Thanks! Glad to see that :-)
However there seems to be an issue when I expand all after the collapse all button as been clicked.
Cannot read properties of null (reading 'push')
eval
/src/DataTableRowGroupDemo.vue:128:31

126 | expandAll() {
127 | this.customers.forEach((p) => {
128 | this.expandedRowGroups.push(p.representative.name);
Any idea?

Yes, It was my mistake. Could you check again collapseAll function? It should be

Code: Select all

this.expandedRowGroups = [];
not

Code: Select all

this.expandedRowGroups = null;
