SelectCheckboxMenu panel not move with its own button when scroll the page
I'm using primeface 6.1

Code: Select all

<p:column rowspan="2" colspan="1">
	<p:selectCheckboxMenu  id="menu"  class="modify-licCopy-btn"  disabled="#{licenseVO.availableLicCopyNumb == 0}"
		value="#{licenseVO.selectedLiccopySerialNo}"  label="modify"  panelStyle="width:250px">
			<f:selectItems value="#{licenseVO.liccopySerialNo}" />
					<p:ajax event="change"listener="#{waitPrintLicenseView.modify}" />
			<f:param name="index" value="${loop.index}" />
	</p:selectCheckboxMenu>
</p:column>
