Better support MultiPoint and MultiLineString about nebula.gl

[supersonicclay]

You can use DrawLineStringMode. If you set selectedFeatureIndexes=[] then it'll draw the first segment. But after you get the first call to onEdit, then you want to set the selectedFeatureIndexes prop to the new feature index in order to extend that line.

So for example:

• pass mode=DrawLineStringMode
• pass selectedFeatureIndexes=[]
• user clicks twice to draw first line segment
• nebula calls onEdit with feature index 5 (because you have 5 features already, nebula is adding a sixth at index 5)
• pass selectedFeatureIndexes=[5]
• now user will be able to click to extend the line string to additional points

MultiPolygon support implemented in #102

Maybe this is already added, but is there a MultiLineString mode?

[georgios-uber]

@titivermeesch it is supported to be edited but not created.

@georgios-uber So now way of creating a path at the moment? Or am I using the feature wrong. The main purpose is to make a path between 2 locations following a road for example

[titivermeesch]

I see how that would work. But does that mean that the user will have to start drawing every time or will the drawing mode remain so the user can continue drawing a line without stopping

[supersonicclay]

Yes, users can draw a continuous line string. Probably the best way forward is to see it in action at https://nebula.gl/geojson-editor/ and select "Draw LineString" on the left side.
