--- layout: example.html title: Interaction Options shortdesc: Shows interaction options for custom scroll and zoom behavior. docs: > 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`. tags: "trackpad, mousewheel, zoom, scroll, interaction, fractional" ---
