multi select dropdown explaination

[rahul234dabas]

Hi,

can anyone explain to me how to deal with multi select dropdown i.e. in which we can select multiple values in one dropdown 

can anyone tell me the properties that need to be different than normal dropdown and how to store the output from the multi dropdown?

Hi @rahul234dabas,

You can consider it be a string array, comma separated. You can refer the tag selection as well, when we use multiple tags to a resource, it is stored as String[] and this use case is analogous to it.

@rahul234dabas As replied in the below thread, the same works for this case as well but only additional property you need to add is mutliple =true and the values will be stored in comma separated string. 

<datatype
    jcr:primaryType="nt:unstructured"
    sling:resourceType="granite/ui/components/coral/foundation/form/select"
    fieldLabel="Select country"
    multiple="true"
    name="./country">

 Hope this helps.

Hi @Siva_Sogalapalli , I tried adding this property and got success but I am trying to get the string array values but getting failed. Please find the below snippet I used:

@ValueMapValue

private String[] fileType; 

private String fileTypeValues;

@PostConstruct

protected void fileExtanctions() { 

if (fileType != null && fileType.length > 0) {  

fileTypeValues = Arrays.stream(fileType).collect(Collectors.joining(", "));  

} else {  

fileTypeValues = "";  

}  

}

public String getFileTypeValues() {

return fileTypeValues;

}

But I am unable to get the string array initially. Can you please help me with this?
