title: Interaction Options

shortdesc: Shows interaction options for custom scroll and zoom behavior.

|
|
This example uses a custom `ol/interaction/defaults` configuration:
|
|
|
|
* By default, wheel/trackpad zoom and drag panning is always active, which
|
|
can be unexpected on pages with a lot of scrollable content and an embedded
|
|
map. To perform wheel/trackpad zoom and drag-pan actions only when the map
|
|
has the focus, set `onFocusOnly: true` as option. This requires a map div
|
|
with a `tabindex` attribute set.
|
|
* By default, pinch-zoom and wheel/trackpad zoom interactions can leave the
|
|
map at fractional zoom levels. If instead you want to constrain
|
|
wheel/trackpad zooming to integer zoom levels, set
|
|
`constrainResolution: true`.
