Can i set content dynamically from block API ?

You can update the block's content in this way

const dblock = blockManager.get('dynamic-nav');
dblock.set('content', `<ul>...`);

Oh i see , thank a lot @artf

Hi, @artf I have a problem, my dynamic-nav's block works now, but when I give some script to that component its give me an error Unexpected identifier. May I correct? if not please correct me, thank you very much

That's my script :

...
          // Dynamic navigation
          blockManager.add('dynamic-nav', {
            label: 'Dynamic Navigation',
            attributes: {
              class: 'fa fa-ellipsis-h',
              title: 'Insert Dynamic Menu of Navigation'
            },
            category: 'Section',
            content: {
              script: function () {
                var contentDynamic = "";
                var xhr = new XMLHttpRequest();

                contentDynamic += `<div id="dynamic-nav-wrapper" class="nav-wrapper" data-section-type="dynamic-menu-nav">
                <a href="index.html" class="brand-logo"><img src="images/logo.png"></a>
                <a href="index.html" data-activates="mobile-demo" class="button-collapse"><i class="material-icons">menu</i></a>
                <ul id="dynamic-page" class="right hide-on-med-and-down">`;

                xhr.onreadystatechange = function() {
                  if (xhr.readyState == XMLHttpRequest.DONE) {
                    var pages = "";
                    pages = JSON.parse(xhr.responseText);
                    for (var i = 0; i < pages.length; ++i) {
                      console.log(pages[i]);
                      if (pages[i].uuid == "<%= page.uuid %>") {
                        contentDynamic += `<li class="current"><a href="${pages[i].url}">${pages[i].menu_name}</a></li>`;
                      } else {
                        contentDynamic += `<li><a href="${pages[i].url}">${pages[i].menu_name}</a></li>`;
                      }
                    }
                  }
                }
                xhr.open('GET', '/dev/editor/dynamicnav', true);
                xhr.send(null);
                contentDynamic += `</ul></div>`;

                this.innerHTML(contentDynamic);

                console.log('the element', this);
              },
            }
          });
