Make side panel shrink to fit children?

[Saithe6]

I'm trying to make a left panel grow with the size of textedits inside it and shrink back down to minimum size when possible.
this is what it looks like before making it grow

I can make it grow by typing

but then it stays big

I can't find anything that would tell me how to do this.
here's the code for the panel

    fn left_panel(&mut self,ui:&mut Ui) {
        egui::SidePanel::left("left_panel")
            .min_width(160.0)
            .resizable(false)
            .show_inside(ui,|ui| {
                let ui_builder = egui::UiBuilder::new();
                ui.scope_builder(ui_builder,|ui| show_stats(ui,self));
                ui.separator();
                self.skills.list(ui,&mut self.insert_mode);
                ui.separator();
                ui.horizontal(|ui| {
                    egui::TextEdit::singleline(&mut self.character_resource.name)
                        .clip_text(false)
                        .background_color(Color32::TRANSPARENT)
                        .frame(false)
                        .hint_text("...")
                        .desired_width(20.0)
                        .insertable(ui,&mut self.insert_mode);
                    ui.with_layout(egui::Layout::default().with_cross_align(egui::Align::Max),|ui| {
                        egui::DragValue::new(&mut self.character_resource.count)
                            .speed(0.05)
                            .range(0..=5)
                            .suffix("/5")
                            .insertable(ui,&mut self.insert_mode);
                    });
                });
                self.resources.list(ui,&mut self.insert_mode);
                ui.separator();
                let mut harm = |label:&str,harm:&mut String| {
                    ui.horizontal(|ui| {
                        ui.label(label);
                        egui::TextEdit::singleline(harm)
                            .clip_text(false)
                            .background_color(Color32::TRANSPARENT)
                            .frame(false)
                            .hint_text("...")
                            .desired_width(20.0)
                            .insertable(ui,&mut self.insert_mode);
                    });
                };
                harm("Minor:",&mut self.minor_harm_0);
                harm("Minor:",&mut self.minor_harm_1);
                harm("Major:",&mut self.major_harm);
                ui.separator();
                if ui.button("Action Roll").clicked() {
                    // self.dice_rollers.action.open();
                };
                // if self.dice_rollers.action.is_open() {
                //     let roll_modal = egui::Modal::new("dice_pool_modal".into());
                //     roll_modal.show(ctx,|ui| dice::show_action(ui,self));
                // }
            });
    }
