This theme disables the default autocomplete functionality of formio.js's
built-in select component and only enables it if the component has an
autocomplete tag in the "Field tags" input of the "API" tab on the form.io portal:
Translation
We patch the customOptions of every autocomplete component at runtime to
include translated (or, at least, translatable) UI strings with predictable
keys that can be customized either globally (all autocomplete components in a
single form) or for each instance. These are the options that Choices.js lets
us localize:
| Option | English | Notes |
|---|---|---|
searchPlaceholderValue |
"Type to search" | The placeholder text of the search input |
noResultsText |
"No results found" | |
itemSelectText |
none | Displayed on the right side of the dropdown alongside the currently highlighted option |
maxItemText |
"Only {{count}} values can be added" | The {{count}} placeholder is substituted with the maxItemCount option. |
noChoicesText |
"No choices to choose from" | This should only show up if we haven't provided any static options or have a dynamic select driven by an API that doesn't return any results. |
addItemText |
none | ⚠️ I think that this option is only applicable when freeform values are allowed. If so, this shows up when you've typed a search string as a prompt, e.g. "Press Enter to add {{value}}", where {{value}} is substituted with the "backend" value of the option. |
To translate these for all autocomplete components in your form, you'll need to
prefix each option with the autocomplete. prefix. So, to translate the text
that shows up when no items match the typed value, you would add translations
for the autocomplete.noResultsText Phrase key.
You can also translate these strings for individual components by prefixing
autcomplete.{option} with the component's key and a .. For instance, if you
had an autocomplete component with the key yourJob and wanted to translate
the placeholder text, you would add translations for the
yourJob.autocomplete.searchPlaceholderValue Phrase key.
The default translations for the autocomplete.* keys live in this repo's
i18n directory and can be updated from the generic strings Phrase project.
