Its functionality is similar to the lookup multiple choice variable, which creates radio buttons from queried data. For attributes supported by this variable, see [variable attributes](https://www.servicenow.com/docs/08IBEw8FtGunfRviPgdk6Q "There are a few Service Catalog variables support specific attributes to define the behavior and restrictions for variables."). To create the lookup select box, enter the following values when creating the variable: * Lookup from table: `Incident [incident]` * Lookup value field: `Sys ID` * Lookup label field: `number, category, priority` * Reference qual: `caller_id=javascript:gs.getUserID()^active=true` {#lookup-select-box__ul_z51_2rw_dq} Note: * Table with large data causes performance issues when loading the page. Use reference qualifiers to reduce data or use the reference type variable. * You cannot add more than 10,000 choices. {#lookup-select-box__ul_lgj_qw1_j3b} **Related concepts** * [Attachment](https://www.servicenow.com/docs/QO6tabzhZQAmG~fTm~Oxvg "When submitting a catalog item request, this variable lets you upload an attachment for a question of the item.") * [Break](https://www.servicenow.com/docs/ZPkcnLIOoUJ0KUAwbkZq1Q "The break variable displays a horizontal line across the form.") * [Check box](https://www.servicenow.com/docs/dbzfzFBOnL0cGsYHCyY0ew "The check box variable lets you enable and disable options by selecting and clearing it.") * [Container start, container split, and container end](https://www.servicenow.com/docs/pC3s_06HYIQ2nYqGR3zVTQ "The container start, container split, and container end variables define a layout for a container that can hold more variables.") * [Date, Date and time, and Duration](https://www.servicenow.com/docs/uzlw6WNmuwB3x01yjFA0pQ "The date variable creates a widget with a field and calendar to select a date.") * [Email](https://www.servicenow.com/docs/e05Xnwb1dlr3HvDFYMK85w "The email variable creates a widget to enter and select an email address.") * [HTML](https://www.servicenow.com/docs/vEd~WSLcnLEnCKxB4dWLrw "The HTML variable lets you provide content with advanced formatting, including images, for a catalog item.") * [IP Address](https://www.servicenow.com/docs/qSWnkVruJD2Cbdub~ODQ2w "Use the IP address variable to specify the IPv4 and IPv6 data for a catalog item.") * [Label](https://www.servicenow.com/docs/55~SxLwA_bs95JADgcA79w "The label variable displays a label across the form.
