API

CONFIG

• id - string - used when saving data to local storage, set different id if there are multiple filters per page to avoid interference - if not set it defaults to “dynamicFilter”
• saveState - boolean - save filter state to localStorage, filter will be in same state after page reload
• autoApply - boolean - execute callback on each filter change
• callback - function - callback to execute on autoApply or manual, as result returns key-array object
• errorCallback - function - receive filter error data as callback, ie. to handle error messages from controller

OPTION

NOTE: This is example of one option object. DynamicFilter accepts array of this objects for initialization.
Let’s see a basic example:

• type - enum - OPTIONS/TEXT/AUTOCOMPLETE (Check input types details)
• label - string - custom label text will be displayed in main option selection
• field - string - this will be key of object which is generated as a result Usually this is table field from backend
• options - string array for selection

Examples for all types:

OPTIONS

type: "OPTIONS",
label: "Material",
field: "material",
options: $scope.dataSource.map(function(m) { return m.name })

AUTOCOMPLETE

type: "AUTOCOMPLETE",
label: "Material",
field: "material",
params: {
     querySearch: $scope.querySearch
}

TEXT

type: "TEXT",
label: "Material",
field: "material"
