[Feature Request] Data Table expand all expandable per default

[eggnaube]

New Functionality

Expand all slots on a v-data-table per default. Currently i have to click each row to expand.

Improvements

I have to iterate all rows and emit a click event.

Bugs or Edge Cases it Helps Avoid

Invalid "expanded" value on row.

[zikeji]

Sounds like the user wants an "expandAllByDefault" prop of some sort.

@nekosaur thoughts on this?

[nekosaur]

I think we should perhaps expose the internal expanded array through a .sync prop, similar to how we do it for selected through the v-model. That way you can easily get the functionality request in this issue, and you get fine-grained external control of expanded rows.

+1 for this feature

Please don't post comments saying +1. Github added reactions where you can voice your interest and have it be sortable for the devs. Thank you

Is this something you think you can still do for v1.1 @nekosaur ?

Could anyone please let me know if this feature was ever implemented and if so how to use it ? I can't seem the workaround to get to work it is not letting me compile.

[MestreKarin]

@AakifMushtaq I got this error too, so I typecast to any and compiled with no errors.

let table: any = this.$refs.dTable;
this.$set(table.expanded, item.name, true);

[VitalickS]

Try look at this example
<v-data-table :expanded="items" .... >
or
<v-data-table :expanded.sync="copyArrayOfItems" .... >
First way just expand all items; second way for tracking selected items by copyArrayOfItems

[miryamfv]

@VitalickS yes that works

[darkbasic]

Shouldn't expanded be a v-model instead, like for the selected rows?
