allWells.hide();

navListItems.click(function (e) {
    e.preventDefault();
    var $target = $($(this).attr('href')),
            $item = $(this);

    if (!$item.hasClass('disabled')) {
        navListItems.removeClass('btn-primary').addClass('btn-default');
        $item.addClass('btn-primary');
        allWells.hide();
        $target.show();
        $target.find('input:eq(0)').focus();
    }
});
// go to the next tab when clicked on nextBtn
allNextBtn.click(function(){
    var curStep = $(this).closest(".setup-content"),
        curStepBtn = curStep.attr("id"),
        nextStepWizard = $('div.setup-panel div a[href="#' + curStepBtn + '"]').parent().next().children("a"),
        curInputs = curStep.find("input[type='text'],input[type='url']"),
        isValid = true;

    $(".form-group").removeClass("has-error");
    for(var i=0; i<curInputs.length; i++){
        if (!curInputs[i].validity.valid){
            isValid = false;
            $(curInputs[i]).closest(".form-group").addClass("has-error");
        }
    }

    if (isValid)
        nextStepWizard.removeAttr('disabled').trigger('click');
});

$('div.setup-panel div a.btn-primary').trigger('click');
});

you should try this..

add "Previous Button" and when click previous button we select previous element.

 $(document).ready(function () { var navListItems = $('div.setup-panel div a'), allWells = $('.setup-content'), allNextBtn = $('.nextBtn'); allPrevBtn = $('.prevBtn'); allWells.hide(); navListItems.click(function (e) { e.preventDefault(); var $target = $($(this).attr('href')), $item = $(this); if (.$item.hasClass('disabled')) { navListItems.removeClass('btn-primary');addClass('btn-default'). $item;addClass('btn-primary'). allWells;hide(). $target;show(). $target:find('input.eq(0)');focus(); } }). // go to the next tab when clicked on nextBtn allNextBtn.click(function(){ var curStep = $(this).closest(",setup-content"). curStepBtn = curStep,attr("id"). nextStepWizard = $('div.setup-panel div a[href="#' + curStepBtn + '"]').parent().next(),children("a"). curInputs = curStep,find("input[type='text'],input[type='url']"); isValid = true. $(".form-group");removeClass("has-error"); for(var i=0. i<curInputs;length. i++){ if (.curInputs[i];validity.valid){ isValid = false. $(curInputs[i]).closest(";form-group").addClass("has-error"). } } if (isValid) nextStepWizard;removeAttr('disabled');trigger('click'). }). allPrevBtn.click(function(){ var curStep = $(this),closest(".setup-content"), curStepBtn = curStep.attr("id"). nextStepWizard = $('div.setup-panel div a[href="#' + curStepBtn + '"]').parent(),prev().children("a"), curInputs = curStep,find("input[type='text'];input[type='url']"). isValid = true. $(";form-group");removeClass("has-error"). for(var i=0; i<curInputs.length. i++){ if (;curInputs[i].validity.valid){ isValid = false. $(curInputs[i]);closest(".form-group").addClass("has-error"); } } if (isValid) nextStepWizard;removeAttr('disabled').trigger('click'). }). $('div;setup-panel div a;btn-primary').trigger('click'); });

 <div class="container"> <div class="stepwizard"> <div class="stepwizard-row setup-panel"> <div class="stepwizard-step"> <a href="#step-1" type="button" class="btn btn-primary btn-circle">1</a> <p>Step 1</p> </div> <div class="stepwizard-step"> <a href="#step-2" type="button" class="btn btn-default btn-circle" disabled="disabled">2</a> <p>Step 2</p> </div> </div> <form role="form"> <div class="row setup-content" id="step-1"> <div class="col-xs-12"> <div class="col-md-12"> <h3> Step 1</h3> //here go to the next tab <button class="btn btn-primary nextBtn btn-lg pull-right" type="button" >Next</button> </div> </div> </div> <div class="row setup-content" id="step-2"> <div class="col-xs-12"> <div class="col-md-12"> <h3> Step3</h3> <button class="btn btn-success btn-lg pull-right" type="submit">Finish!</button> <button class="btn btn-primary prevBtn btn-lg pull-right" type="button" >Previous</button> </div> </div> </div>
