javascript - Appending to combobox field in ExtJS -


i have combobox text. when select element dropdown must appended field of combobox not replaced.

i've tried this: 

beforeselect: function (combo, record) {        var rawval = this.rawvalue;         ...............          record.data.value = rawval + record.data.value; }

but code adds store modified version of record, not need. need store haven't modified.

if question clearly, field need tag field not combobox. can check example below link.

http://examples.sencha.com/extjs/6.0.2/examples/kitchensink/#form-tag

you not need record operayion using tag field. if have further question, let me know.
