[EuiComboBox] Custom matcher requested

[flash1293]

The combo box component matches items strictly by checking whether the typed string appears as a substring in the label of one of the options. In same cases it would be beneficial to overwrite this behavior with a custom matching function if that makes sense for the options shown in the combo box.

Example: Combo box with field names - here it would be nice to match by prefix per dot-separated part of the field name, typing r.b.by should match http.response.body.bytes. Especially for ECS like data with long field names and a lot of fields in a single index this makes selecting the right field much easier.

Another example (even though I don't have a specific use case for that) would be a fuzzy search which allows small typing errors like missing characters or swapped characters.

Makes sense to me. I think initially we can just allow for consumers to provide their own matching function. Fuzzy search would be a reasonable thing for EUI to eventually expose in something like the combo box, but rolling your own will likely get you what you want faster.

i tried implementing It but got this as an error

even when I used

options.filter(({ label }) => {
      return label.includes('a'); })

as a custom matcher, This might be because functions in JS are not same and hence ComponentDidUpdate gets repeatedly called.

Currently there's a workaround. According to the source code, the built-in filter is turned off for async comboboxes. So you could just give the filtered options rather than all options to the EuiComboBox component and set async={true}.

Due to the age of the issue we're closing this as not-planned. There is a valid workaround provided by @balthild. If additional functionality is required, please feel free to open an PR.

Re-opening due to recent Kibana need (#7661)

Also note to self when working on this: we should add support to both EuiComboBox and EuiSelectable

We've added a new optional optionMatcher prop in this PR. It will be available in the next version of EUI, which will be released later this week.
