A geographical distance in meters (rounded at two points). Will give an extra minimap with a measurement tool. Arguments: [ zoomlevel, preferredBackgroundMapType (comma separated) ], e.g. `["21", "map,photo"]
A geographical direction, in degrees. 0° is north, 90° is east, ... Will return a value between 0 (incl) and 360 (excl).

| key | the value of this tag will initialize search (default: name). This can be a ';'-separated list in which case every key will be inspected. The non-null value will be used as search |
| options | A JSON-object of type `{ removePrefixes: Record<string, string[]>, removePostfixes: Record<string, string[]>, ... }`. See the more detailed explanation below |
| removePrefixes | remove these snippets of text from the start of the passed string to search. This is either a list OR a hash of languages to a list. The individual strings are interpreted as case ignoring regexes |
| removePostfixes | remove these snippets of text from the end of the passed string to search. This is either a list OR a hash of languages to a list. The individual strings are interpreted as case ignoring regexes. |
| instanceOf | A list of Q-identifier which indicates that the search results _must_ be an entity of this type, e.g. [`Q5`](https://www.wikidata.org/wiki/Q5) for humans |
| notInstanceof | A list of Q-identifiers which indicates that the search results _must not_ be an entity of this type, e.g. [`Q79007`](https://www.wikidata.org/wiki/Q79007) to filter away all streets from the search results |
| multiple | If 'yes' or 'true', will allow to select multiple values at once |
The following is the 'freeform'-part of a layer config which will trigger a search for the wikidata item corresponding with the name of the selected feature. It will also remove '-street', '-square', ... if found at the end of the name

| prefix | Piece of text that will always be added to the front of the generated opening hours. If the OSM-data does not start with this, it will fail to parse. |
| postfix | Piece of text that will always be added to the end of the generated opening hours |
Validates that the slope is a valid number.The accompanying input element uses the gyroscope and the compass to determine the correct incline. The sign of the incline will be set automatically. The bearing of the way is compared to the bearing of the compass, as such, the device knows if it is measuring in the forward or backward direction.
