I have a simple html form with nested jQuery steps.
The Main wizard has 5 steps and the 3rd step has a sub wizard containing 3 steps.
When clicked on "Next" of main wizard, step is moved and the content is displayed but after the 3rd step (the one with sub wizard) the tab moves to the 4rth but upon reaching 4rth step no content is displayed, if I disable the jQuery script that displays the sub wizard, the main 4rth step displays content.
I tried various forums and also started debugging jQuery Steps library for a while now but couldn't find out the reason.
Any help is appreciated.
Here is the code which is also executable.
$("#frmMainWizard").steps({
headerTag: "h3",
bodyTag: "section",
transitionEffect: "slide", // "fade",
stepsOrientation: "vertical"
//enableAllSteps: true,
//enablePagination: false,
});
var childForms = $(".frmWizardSteps");
$.each(childForms, function() {
console.log(this.id);
var currentSubStesId = '#' + this.id;
$(currentSubStesId).steps({
headerTag: "h4",
bodyTag: "div",
transitionEffect: "slideLeft",
stepsOrientation: "vertical"
//autoFocus: true,
//enableAllSteps: true,
//enablePagination: false
});
});
$('#btnPrev').click(function() {
$("#frmMainWizard").steps('previous');
});
$('#btnNext').click(function() {
$("#frmMainWizard").steps('next');

Apparently, the problem is that somehow the onStepChange event handler for the main-wizard is not being called anymore once sub-wizard is initialized and displayed. I may provide additional information after debugging the library. Will keep you updated.
About the solution:
Let's say that we have two functions that initialize main-wizard and sub-wizard by using jquery.steps library.
Function for main-wizard looks like the following:
var shoMainWizard = function(){
$("#main-wizard").steps({
/*
All your jquery.steps config stuff here
plus the following event handlers
*/
onStepChanging: function (event, currStepIndex, nextStepIndex) {
// If we are moving on the step which contains the sub-wizard (index 2)
if (nextStepIndex == 2){
shoSubWizard(currStepIndex, nextStepIndex);
}
return true;
},
onStepChanged: function (event, currStepIndex, priorStepIndex) {
$("#main-wizard-p-" + priorStepIndex).hide();
$("#main-wizard-p-" + currStepIndex).fadeIn();
}
});
};
Note that onStepChanging handler makes the sub-wizard to be initialized and displayed in the first call and just to be displayed in the next calls.
Note also that onStepChanged handler toggles the view by hidding the previous-step view and displayed the next-step view.
Function for sub-wizard looks like the following:
var shoSubWizard = function(currStepIndex, nextStepIndex){
// if sub-wizard note rendered yet
if (!$('#sub-wizard').hasClass('wizard')){
/*
All your jquery.steps config stuff here
plus the following event handlers
*/
onFinished: function() {
$("#main-wizard").steps("next");
}
});
}
// otherwise, display sub-wizard with last changes
else {
$("#main-wizard-p-" + currStepIndex).hide();
$("#main-wizard-p-" + nextStepIndex).fadeIn();
}
}
Note that there is an if statement to identify whether the sub-wizard was already initialized or not by asking if it already has wizard class that jquery.steps adds. In case it was already initialized, we just need to show() it.
Note also that the onFinished handler makes the main-wizard to continue with the next-step.
Hope this helps to solve your problem.
EDIT:
After reviewing and debugging the code, the problem is that following jQuery query (line #1196 from library) gets all steps content from main-wizard and sub-wizard and makes the transition (from the step which contains the sub-wizard to the next step) to be messed up among them.
var stepContents = wizard.find(".content > .body")
Changing that line by the following one fixes the issue. However, there are some other lines that need similar fix.
var stepContents = wizard.find("> .content > .body")
Note also that there is a pull request pending to approve that apparently fixes the issue. However, IMHO, that pull request changes directly the built file from the library, and it probably won't get approved.
EDIT 2:
Pull request created here to fix the issue about having nested jquery.steps wizards.
