Hi, everyone. Can I set logic in file .zul? Like I have any value and I set if a value is 0, then I just show empty textbox, but if a value is more than 0, I show that value in textbox. Can I set that logic in the file of .zul? Thank you..

yes there are several ways to express logic you can:

use a ternary operator (?:) in EL expressions:

${someVariable eq 0 ? '' : someVariable}

use the special zuml attributes (if/unless) to render components conditionally:

<textbox if={someExpression}/>

with ZK EE and zuti.jar use shadow elements <if>/<switch> (since ZK 8)

<if test="${someExpression}">
   <textbox/>
</if>
