APEX form tabs

(APEX 4.2.x)

I have used APEX since 3.2 release and always had a need to implement pages that include tab sub-regions. Since it is quite common user request that is why I posted this to possible offer you one more way of how you can create tabs on your APEX pages. 

There are different solutions out there such as: tab-pluggin or jquery-tabs and few others.

Both solutions are equally good but I wanted something even more simple so this is what I have used.

Cookbook:

1. Download these two scripts:
JavaSript code: 



function stringToPrepend(tabID, class_title){
  //return prepand String based on tabID provided
  // tabID must match corresponding DIVs
 var htmlText = "<ul>";   

  //LOOP through all tab divs where id like SubTabs
 //and create <UL> element
 $("div[id^="+tabID+"]").each(function(i) {
   var position = i+1;
   var tabTitle = $('div[class$=' + class_title + ']:first', this).text(); // template class used here as Title if subregion then use only parent title
 
   htmlText = htmlText
         + "<li><a href=#"
         + tabID
         + position
         + "><span id=span"
         + position
         + ">"
         + tabTitle
         + "</span></a></li>";
 }); //end loop
 htmlText = htmlText + "</ul>";
 return htmlText;
} //end stringToPrepend

function appendTabChild(tabID, base){  
 //LOOP through all tab divs where id like SubTabs
 //and append element to tab
 $("div[id^="+tabID+"]").each(function(i) {
   var position = i+1;
   var tabs = tabID + position;
   if(position > 1){
   $("div[id^="+tabs+"]").css('display', 'none');
   }
   base.appendChild( $x(tabs));  
 }); //end loop
} //end appendTabChild

// end JS

CSS code:

#base {
    padding: 0px;
    background: none;
    border-width: 0px;
}
#base .ui-tabs-nav {
    padding-left: 0px;
    margin-bottom: 2px;
    background: transparent;
    border-width: 0px 0px 0px 0px;
    -moz-border-radius: 0px;
    -webkit-border-radius: 0px;
    border-radius: 0px;
}
#base .ui-tabs-panel {
    background: #f5f3e5 url(http://code.jquery.com/ui/1.8.23/themes/south-street/images/ui-bg_highlight-hard_100_f5f3e5_1x100.png) repeat-x scroll 50% top;
    border-width: 0px 1px 1px 1px;
}
#base .ui-tabs-nav li.ui-tabs-active {
      background: #CCCCCC !important;
}

.ui-state-active a, .ui-state-active a:link, .ui-state-active a:visited {
    color: #296EB3;   
}

.nr-title, .rc-title{
font-size:10px;
}
 

2. Save them as .js and .css files 

3. Upload them into your APEX environment

4. Add this to your APEX page header



<link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script>

<script src="#WORKSPACE_IMAGES#Form_tab.js"></script>
<link rel="stylesheet" href="#WORKSPACE_IMAGES#Form_tab.css">
<script type="text/javascript">

$(function() {

/**************** KEY PARAMETERS

1. create 3 html regions
  - first to be id=base or change the variables in javascript with no template
  - other two id = SubTabs1, 2  or change the variables in javascript 

2. paste this code into page header or include it as java script

WARNING: '-title' class selector used and this might cause Tab title
to be empty if Application template doesn't contain this
**************************************/

//html region ID=base that holds all tabs
var container = $("#base");
var base = $x("base");
var tabs_id = 'SubTabs';
var v_class = '-title'; //// template class used here as Title

//populate container div with extended html
container.prepend(stringToPrepend(tabs_id, v_class));
//append tabs
container.tabs();
appendTabChild(tabs_id, base);
});
// end JQuery function

</script>

5. Create one HTML region as



6. Create the rest of the regions with IDs: SubTabsx  i.e 1,2,3,...... (or change JavaScript)

 

And that is it.

To summarize: Container region is where HTML will be generated.

I have tested this in 4.2.3 and 4.2.5 Theme 22, but I am sure it should work in other themes too. 

The only thing to note is current scripts do not work if parent script does not contain a title. Sub-regions and nested regions should be supported plus nested regions can be without a title.

For any other problem I am sure you should be able to adjust these scripts to your needs. 

CSS file is where you might want to change the appearance of your tabs.

Hope this helps.

........

I have been playing with theme25. The only changes are 
in header:

var v_class = 'Heading'; //// template class used here as Title

in javascript code: 


function stringToPrepend(tabID, class_title){
  //return prepand String based on tabID provided
  // tabID must match corresponding DIVs
 var htmlText = "<ul>"; 


  //LOOP through all tab divs where id like SubTabs
 //and create <UL> element
 $("section[id^="+tabID+"]").each(function(i) {
   var position = i+1;
   //alert($("div[class$='-title']:first", this).text());
   var tabTitle = $('div[class$=' + class_title + ']:first', this).text(); // template class used here as Title if subregion then use only parent title
   //alert('Here: ' + position /*+ $(this).text()*/ + tabTitle );

   htmlText = htmlText
         + "<li><a href=#"
         + tabID
         + position
         + "><span id=span"
         + position
         + ">"
         + tabTitle
         + "</span></a></li>";
 }); //end loop

 htmlText = htmlText + "</ul>";

 return htmlText;
} //end stringToPrepend


function appendTabChild(tabID, base){  
 //LOOP through all tab divs where id like SubTabs
 //and append element to tab
 $("section[id^="+tabID+"]").each(function(i) {
   var position = i+1;
   var tabs = tabID + position;
   if(position > 1){
   $("section[id^="+tabs+"]").css('display', 'none');
   }
   base.appendChild( $x(tabs));  
 }); //end loop
} //end appendTabChild
