DataViewFilters dropdown: Reset active attribute to first item after the filters are cleared

Hi team, we’re using DataView + DataViewToolbar + DataViewFilters. When a user clicks “Clear all filters”, we want the attribute dropdown (in DataViewFilters) to reset to the first filter (our Name/URL) instead of staying on the last interacted attribute.

Right now, we’re nudging React to remount the first child by bumping a key on our Name/URL filter after clear. This works but is fragile/hacky.

Our Proposal

We have a couple of ideas on how to make this work more smoothly for everyone. We'd love to hear your thoughts on either of these solutions:

• Make it the default. We think it would be great if DataViewFilters simply reset to the first attribute whenever filters are cleared. It’s what most users would expect, and it would save a lot of people from having to implement their own workarounds.

• Introduce a new prop. What if we added an optional prop like defaultActiveFilterId? This would give developers the flexibility to explicitly set the default attribute, both on the initial load and after filters are cleared.

Thanks so much for considering our suggestions!

从 DataViewFilters 的实现开始，跟踪现有的“Clear all filters”行为，包括如何选择活动属性。确定清除时是否应始终选择第一个属性，或支持 defaultActiveFilterId prop，然后验证清除筛选器后 dropdown 是否按预期重置。
