App Behaviour

Constraint Height

The normalHeight option will apply a maximum height to each photo item and also adjust the width to keep the item aspect ratio. The purpose of normalHeight is to apply constraints on photo dimension so they are not too big which help improving aesthetics and app performance.

Sorted Item

The autoSorted option will sort input items according to their width, so the smaller items will be seen before the bigger items. If you don’t like this behaviour simply set the option to false to disable it.

Shifting Mode

When browsing through the gallery, current items are moved or shifted out of the view to reveal the items behind. The option ‘shiftMode’ dictates the animations and transitions used to move the items. There is a total of 14 shifting modes:

Name	Description
normalHeight	Constraint height applied to each item
left	Items are shifted left
right	Items are shifted right
leftRight	Items are shifted left and right alternatively
top	Items are shifted up
bottom	Items are shifted down
topBottom	Items are shifted up and down alternatively
spiral	Items are shifted down and rotated like a spiral
spiralReverse	Items are shifted down and rotated like a spiral reversely
spiralUp	Items are shifted up and rotated like a spiral
spiralUpReverse	Items are shifted up and rotated like a spiral reversely
reveal	Items are shifted down and rotated and remained in close distance
revealReverse	Items are shifted up and rotated and remained in close distance
flip	Items are flipped up and down
