        }

        render() {
            return (

###Props:

  • fields: your fields used to build a query

    • name: name of the field that would be used in a query
    • label: how your field name would be shown in the dropdown
    • operators: remove this property or set to 'all' if you want to use all operators for this field, else you can limit them by passing the array of the allowed operators ['=', '<', '>']
    • input: type of the input, possible options are: text, textarea, select. If you are using select input type pass options to the object in the following way: input: {type: 'select', options: [{value: '1', name: 'one'}, {value: '2', name: 'two'}]}. Also, it supports validation by passing pattern property with regexp pattern and errorText property for validation error message text.
  • onChange: pass here your function that will be called when data was changed

  • config: configuration object with possible options:

    • query: pass here prepared query, so UI will be built using it.

        { operator: '>', label: '>' },
        { operator: '>=', label: '>=' },
        { operator: '<=', label: '<=' },
        { operator: 'IS NULL', label: 'Null' },
        { operator: 'IS NOT NULL', label: 'Not Null' },
        { operator: 'IN', label: 'In' },
        { operator: 'NOT IN', label: 'Not In' },
       ]
      
    • combinators: array of combinators, the default one is:
