/**
 * @whatItDoes
 *
 * The LookupDropdown component represents all the values on a lookup table as a dropdown where the user can pick one or more values.
 * It uses the inner dropdown component to adapt to the position where the dropdown is placed.
 * This component loads the dropdown values from the cache
 *
 * @howToUse
 *
 * This component requires at least the lookupTableId or the lookupTableName to work, so it can resolve the values being shown.
 * You should use it in a filter like component. For picking a value in a form please refer to LookupCombobox component
 *
 * ### Inputs
 * `string` : **lookupTableId** - The table name to resolve the values from
 * `string` : **lookupTableName** - The table id to resolve the values from
 * `string[]` : **itemsToIgnore** - An array of items to ignore.
 * The items of the array will be compared with both keys and values of the lookup table
 * `string` : **mainTitle** - Title being displayed on top of the lookup dropdown
 * `string` : **subTitle** -  Defines the component sub title for the top of the dropdown
 * `boolean` : **search** -  Defines if the inner component has search on the dropdown to type text and look for the values
 * `boolean` : **multiSelection** -  If enabled, will allow the selection of multiple lookup table values
 * `string` : **allName** - String to show when all / none items are selected
 * `boolean` : **disabled** - If set to true, will disable the selection of a value and the opening of the dropdown
 * `boolean` : **required** - If set to true will trigger the validation of the value (has to be different than null)
 * `Cmf.Foundation.BusinessObjects.LookupTableValue | Cmf.Foundation.BusinessObjects.LookupTableValue[]` :
 * **value** - Sets the currently selected value on the dropdown
 * `ComparisonMode` : **comparisonMode** - Comparison mode used for selection, by default is strict
 *
 * ### Outputs
 * `Cmf.Foundation.BusinessObjects.LookupTableValue | Cmf.Foundation.BusinessObjects.LookupTableValue[]` :
 * **valueChange** - The value change event, so the component can inform the upper components that the value has changed
 *
 * ### Example
 *
 * ```HTML
 * <cmf-core-business-controls-lookupDropdown
 *     lookupTableName="AreaType"
 *     mainTitle="AREA"
 *     search="true"
 *     multiSelection="true"
 *     disabled="false">
 *  </cmf-core-business-controls-lookupDropdown>
 * ```
