jQuery/JS Common - Object Structures - positionConfig - collision

A string passed to this option should contain a collision handler name, or a pair of names separated by space. If the string consists of a single collision handler name, it is applied to both horizontal and vertical axes. If you pass a pair of names separated by space, the first collision handler will be applied to the horizontal axis, the second to the vertical axis.

// a string containing horizontal and vertical
// collision handlers separated by space
collision: "flip fit";

You can also specify different collision handlers for horizontal and vertical axes in one of the following ways.

// an object containing 'x' and 'y' fields
collision: {
    x: "flip", // horizontal collision handler
    y: "none" // vertical collision handler
}

The available collision handler names are:

• none
  Collisions do not affect widget position.
• flip
  Moves the widget to the opposite side of the target element if it allows more of the widget to be visible.
• fit
  Shifts the widget from outside of the screen to fully display the widget.
• flipfit
  Applies the fit collision handler after flip.

When using a widget as an ASP.NET MVC Control, specify this option using the PositionResolveCollision enum in the following manner. This enum accepts the following values: Fit, Flip, FlipFit and None.

@(Html.DevExtreme().WidgetName()
    .Position(p => p
        .Collision(PositionResolveCollision.Fit, PositionResolveCollision.Flip)
    )
)

@(Html.DevExtreme().WidgetName() _
    .Position(Sub(p)
        p.Collision(PositionResolveCollision.Fit, PositionResolveCollision.Flip)
    End Sub)
)
