Zoom control
The Zoom control places the standard ArcGIS zoom in / out buttons on the map. It is the only control placed by default (top-left corner) on a new map.
What it does
Adds the native arcgis-zoom buttons so viewers can step the view in and out
without the mouse wheel. It complements—rather than replaces—mouse-wheel zoom,
which is governed separately by the Show feature popup group's
Mouse-wheel zoom toggle.
Configuration
| Field | Type | Default | Purpose |
|---|---|---|---|
controls.zoom | ControlPlacement | null | { corner: "top-left" } | Corner placement, or null to hide. |
A ControlPlacement is { corner, inExpand } where corner is one of
top-left, top-right, bottom-left, bottom-right and inExpand tucks the
control inside that corner's expand container.
In the config panel
Open Appearance → UI controls and drag the Zoom chip onto a map corner. Drop it on the corner's Expand chip first if you want it grouped inside an expand. Drag it back to the tray to hide it.
Behavior
- Renders directly in its corner, or inside the corner's expand when
inExpandis set. - Hidden when its placement is
null; mouse-wheel zoom still works unless that is separately disabled.
